Very easy to build up one of EL84 Single Ended Amplfier then I tested at all ,getting Df 2.2 at 1 Khz and rms power is 4.5 W max.
very good,DF 2.2 is not so bad value ,,
sound just like a EL34 family sound .EL84 family does not good power if using triode connection so this time using as penthod modo.
long time I am using small vertical twin Yamaha NS 300 91db/m speakers until now and getting sound great.It's enough to use at home.
I like to listen modern classic music like a Vent Vent ,,,by  James Macmillan and mostly using modern Jazz ,piano by Kieth Jarrett and Fusion.
this amplifier getting peak power are almost 4.5W and at 5% distortion is 3.8 W.Freq response are 20Hz to 50Khz -3dB at 1W rms. very natural if using good core of transformer.
how about try to build up these kind of small amplifier ? looks like toy but sound is good enough for your first audio room for 1st time.
but these kind of small power amplifier sound depend on good efficiency speaker.at least need 91dB/m/w or more.
I think easily to make one of amplifier by your pocket money.???from US $100 ~ $ 250 ..will be fine..But you have to seach where to get component in your country and electronics shop and some time good get from digikey and rs component in your country.

Mr Yoshio Nasu writer and builder of valves Amplifier in Japan .Mr Nasu is writer name. real name is Mr Suzuki ex owner of ISO Tango.this small amplifier designed by
Mr Nasu( Mr Suzuki )he made many of amplifier from a to z. even 300B and RCA 50 Single Ended Amplifier and many push pull amplifier too.
let's me show you one of old book of Mr Nasu. call it's 「Produced a collection of 24 different tube amp to be able to make sure」
this old book is still Has been published under IAR Japan.but only Japanese version can to get. book
please ask to them if would like to get good book but only Japanese version.inside show 6V6,VT62,45,50,6BX7,2A3,6BQ5,DA60,6BM8,843,6CA7,50 as single ended amplifier.
and VT52,6F6,KT66,2A3,6V6G,6BQ5,6L6 as Push Pull Amplifier.and few pre amplifiers.all of Amplifier using off course Tango Transformer.

How to fixed position of Power Transformer and Audio Transformer

As you know ,,Power Transformer made some noise( Ham noise)from AC line through to Audio Transformer .always each power transformer core and Audio Transformer line are
90 degree vertical. exactly how to make position of each transformer are,,,please see how to make fixed position of Audio Transformer
ans Power transformer on chassis. and made ground line in chassis.
and see Ground line how to makevery important.when make plan to build up one of valve amplifier.

ground line

ground line(we call it's mother line in Japan)kind of Cupper wire 2 m/m just like photo.some time use nickel wire or gold wire too)


AnySingle Ended Amplifier getting one of problem with Hum noise from Power Transformer.
so one's have to test for postion of transformer position before fixed up position of transformer.
relationship of positon of audio transformer and power transformer are always 90 degree core of each other.
many expensive Japanese Transformer are "does not care position of transformer".because
they are already has shield.both way of electric shield and magnetic shield.but make sure must test position each other.
like next

Mr Vidal his small audio line in concepcion chile

Still he is using TA2020 digital amplifier and EL84 Single ended amplifier in Chile


Circuit diagram show

above png file.I got 2 of different EL84 one of JJ and
EH . both are good but JJ is a little bit narrow sound to get other wise EH is
very wide range. power transformer is 250V 100mA small one.out put transformer are
Toei trans Co Japan OPT-5S ( 5W 40Hz  small transformer  US$ 19 each ) 1/3 size of
Tango U-808.valve are 1 of 6AQ8(ECC85) and EH EL84 .they are better than any other
combinations.EH EL84 is very good tone has.even Mullard EL84 old tube if you can
get too.with 6AQ8 and Mullard EL 84 using very beautiful sound you can get and instead of ECC85(6AQ8) can be use 6DT8 .just like same sound of 6AQ8(ECC85).same circuit can be use for EL34 single ended amplifier only 2 parts need replace ,Power Trans and Out put transfomer for mejor type.

I am using small one

and I think many person heard 1st time this
Toei transfomer Co Japan.they are  making  many  small  transfomer  for
maching  transfomer as a PA system.and making some of clone of Tango trans recently. OPT-5S is clone of Tango U-608 .same you can use
Hammond mini transfomer 125CSE instead of Toei Transformer.
next one is same circuit as above but added 2 volume control and 2 Input line.
valuve are same family can be use .like a 6BQ5 and 7189 audio tubes.





dimension : 230mm X 160mm X 120mm(high) very cute amplifier but sound like
EL 34 Single Ended Amplifier .just enough to use your living room.

Audio Transformer informations

show you 2 type of Transformer one is Touei Transformer and other one is Kasuga Transformer.both are for 5 W Single Ended Amplifier.
Touei is OPT-5 (OPT-5SR) for Lower frequency amplifier suppose be for Jazz, Violin Classic, Rocks
Kasuga is KA-54B57 (KA-54B57T)for plan . reach to high frequency response for Fusion and Classic.
almost each other diffrent maker but almost same price.

About EL 84 Single Ended Amplifier comments in Spanish ,santiago chile 12nd Aug 2004
Un gran mini amplificador

Si hay alguna palabra que puede resumir el caracter del sonido del mini
amplificador EL84 es suavidad. El sonido en todo el espectro sonoro es de
una suavidad que nunca llega a la exageracion de distorsionar gravemente
los sonidos. Y la nitidez que subyace a esta extraordinaria suavidad
musical es fuera de lo comun, y ciertamente nunca escuchada en equipos de
precio tan economico como este mini amplificador EL84. Escuche varios CDs
que conozco bien a trav� de un lector de DVD Toshiba, modelo SD3109, y
con mis parlantes preferidos, los Altec Modelo A7.

El magnifico CD de Diana Krall, The Girl in the Other Room (Universal), a
traves del EL84 adquiere una presencia escenica abrumadora, con la
magnifica confluencia del piano y la voz de la extraordinaria interprete,
amalgamada a la perfeccion con el contrabajo, el piano y una bateria que
es sensualmente suave y nunca estridente. El impresionante comienzo de
Stop this World, con un piano tan dulce que no deja ver su cualidad de
cuerdas percutadas, anuncia ya una grabacion de calidad sobresaliente. En
The Girl in the Other Room la presencia de Diana Krall al frente de los
parlantes, con su exquisita modulacion y tecnica perfecta, hacen que su
respiracion nos transporte al ambiente intimo de una sala de jazz, con su
voz envuelta en el acompanamiento de musicalidad extrema de sus
acompanantes. En Narrow Daylight la guitarra hace un delicioso dialogo con
la cantante, con cada una de sus cuerdas llegando nitidamente a uno con el
equilibrio perfecto entre fidelidad y suavidad del sonido del mini
amplificador EL84.

Pero un amplificador puede ser sobresaliente en musica intima y al mismo
tiempo carecer de la capacidad de resolucion sonora ante musica orquestal
compleja. Musica intima en este contexto significa de rango dinamico
reducido y cuya relativa pobreza en instrumentos implica una variedad
reducida de timbres sonoros. Esto se observa frecuentemente en equipos
musicales transistorizados o a tubos de bajo costo. Bueno, ciertamente no
este el caso del mini amplificador EL84, el cual tambien es de una
perfeccion sonora extrema ante musica orquestal compleja.

La Sinfonia N� 40 de WA Mozart interpretada por Nikolaus Harnoncourt
(Teldec) revivio con una delicadeza a la altura de este gran director. El
casi exagerado fraseo y modulacion del tiempo que hace esta orquesta bajo
la direccion de Harnoncourt, entregan una notable interpretacion de
camara, que sin embargo mantiene el caracter sinfonico de una obra muchas
veces interpretadas por orquestas mucho mas numerosas. La intensidad
controlada que impregna a esta sinfonia alcanza probablemente su climax en
el tercer movimiento, donde el juego de contrapunto lleva la memoria
irremediablemente a JS Bach, sin que nunca le falte aire al amplificador
para reproducir todo el rango dinamico de la orquesta. El ultimo
movimiento libera la energia contenida del tercero, finalizando en un
juego de melodias sublimes que despliega toda la maestria superior de la
forma, la orquestacion, la armonia y el contrapunto que en WA Mozart son
la culminacion de un estilo y el augurio de la musica venidera. El noble
mini EL84 revivio en forma perfecta la interpretacion grabada en vivo, con
instrumentos de epoca y la orquestacion original de WA Mozart, entregando
con definicion y nitidez a cada uno de los instrumentos, pero sin
destacarlos exageradamente sobre el todo de la orquesta. Uno no puede
dejar de pensar que esta magica experiencia entregada por el
extraordinario mini EL84, solo puede ser superada por una audicion en
vivo, al frente de la orquesta.

Y si se quiere poner a prueba la suavidad y musicalidad del mini amp
EL84, una prueba de fuego es el Concierto para Orquesta de Bartok. La
interpretacion de Bernard Haitink al frente de la Royal Concertgebouw
Orchestra (CD de Philips) es bellisima, y los bronces y los violines, y
aun las inevitablemente estridentes trompetas, reviven a traves del mini
EL84 con una dulzura sobrenatural, sin que se pierda ni un apice de la
fuerza de la orquesta en la sucesion de fortes impregnados de bronces que
salpican la orquestacion de Bartok hasta el final de la obra.

Conseguir esta altisima alta fidelidad, manteniendo el precio en un rango
muy bajo, es otro de los logros del circuito y manufactura del mini
amplificador EL84, disenado y fabricado con una simpleza clasica, siempre
poniendo la electronica al servicio de la musica.


Dr Hugo Cardenas

Great mini amplifier
If there is any word that can sum up the character of the sound of the mini
EL84 amp is striking . The sound throughout the sound spectrum is
a smoothness that never reaches the exaggeration of seriously distorting
sounds . And sharpness behind this extraordinary softness
music is out of the ordinary , and certainly never heard in teams
as affordable price as this mini amplifier EL84 . Hear various CDs
I know well trav a Toshiba DVD player model SD3109 , and
my favorite speakers, the Altec Model A7 .


The magnificent CD Diana Krall , The Girl in the Other Room (Universal ) , a
through the EL84 acquires an overwhelming stage presence , with magnificent confluence of the piano and the voice of the extraordinary interpreter, amalgamated to perfection with bass, piano and drums that is sensually smooth and never harsh . The impressive start Stop this World , with a sweet piano that belies its quality of percutadas strings , and announces a recording of outstanding quality. in The Girl in the Other Room Diana Krall 's presence in front of the speakers, with its exquisite and perfect modulation technique, make your breathing shuttle us intimate atmosphere of a jazz club , with its voice shrouded in extreme musical accompaniment of his companions . In Narrow Daylight guitar makes a delightful dialogue with singer , with each of its strings coming neatly with one perfect balance between smoothness and fidelity Mini sound EL84 amplifier .
But an amp can be outstanding in intimate music and at the same time lack the capacity to orchestral music sound resolution complex . Musica intima in this context means the dynamic range reduced relative poverty and whose instruments involves a variety reduced sound timbres. This equipment is often observed in musical transistor tubes or low cost. Well, certainly not the case of the mini amplifier EL84 , which is also a extreme sound to perfection complex orchestral music .
The Symphony No. 40 by Mozart performed by Nikolaus Harnoncourt ( Teldec ) revived with a delicacy at the height of this great director . the almost exaggerated phrasing and modulation of time makes this orchestra under Harnoncourt 's address , delivered a remarkable interpretation of camera, yet maintains the symphonic character of a work many sometimes interpreted by much more numerous orchestras . intensity controlled that permeates this sinfonia probably reaches its climax in the third movement , where the game takes counterpoint memory JS Bach hopelessly without ever lacks air to the amplifier to reproduce the entire dynamic range of the orchestra. the last movement releases the energy contained in the third , ending a sublime melodies game that displays all of the top Masters form, orchestration , harmony and counterpoint in WA Mozart are the culmination of a style and omen of the coming music . the noble EL84 mini revived in perfect shape the interpretation recorded live with era instruments and the original orchestration of WA Mozart , delivering with definition and clarity to each of the instruments, but outrageously highlight them on all of the orchestra. One can not help thinking that this magical experience delivered by the special mini EL84 , can only be overcome by a hearing in Live , in front of the orchestra.
And if you want to test the smoothness and musicality of the mini amp EL84 , a test is the Bartok Concerto for Orchestra . the interpretation of Bernard Haitink leading the Royal Concertgebouw Orchestra ( Philips CD ) is bellisima , and bronzes and violins , and even the shrill trumpets inevitably , revived through the mini EL84 with preternatural sweetness , without losing one iota of strength of the orchestra in the succession of fortes impregnated bronzes Bartok 's orchestration dot to the end of the work. Get this ultra high HiFi, keeping the price in a range very low , is another achievement of the circuit and manufacturing of mini EL84 amp , designed and manufactured with a classic simplicity , always putting the electronics in the service of music .

EL86 single ended amplifier

EL86 Single Ended Amplifier with Active UL

EL86 Single EndedAmplifier D.I.Y on 2012

This Amplifier using 6CW5(USA) and EL86(Europa) ,TV vertical valve using for Power.
one thing very similar valve with EL84 but charactor is very different.low plate voltages and
high plate current.physically very similar each other valves.but just different sound.


Appendix 1



frequency response are 10Hz to almost 50KHz at -1dB 1W rms



Power is max 4.5 W rms at 0.35V rms input level.not reach to 5W cause
by small transformer use.but sensitivity is very nice.

Speaker system Made in Chile .Cajas Acusticas Chile with 45 Single Ended Amplifier hereto click.



My audio system 2005
46+ 45

Left Channel is 46 sylvania and Right channel is 45 tung-sol
Just say 2type of triode diffarent combination.
46 is slightly narrow so make a NFB from 1 st stage of cathode to 2ndly of out put transfomer
around 4-5 dB of NFB and replace final stage coupling capaciotr 0.68uF to 0.2 uF .45 is non NFB.46 is
only 1.2 W Power I got . very great sound ,like a RCA 45 .but a little bit different.
clear sound from low and mid .so 45 obtain very clear sound from low to high
therefore 45 Single Amplifier is , I guess better than 300B SE original even 2A3 RCA SE,only 45 is around 1.5 to 2.0 W rms.problem but enough to use living room with some over 90 db/m speaker system.
if you use big size of out put transfomer will be get good sound from 45.
46 is g2 connect with plate .can be usr 47 triode connection ,but sound get like a pentode. 26th Feb 2005.

Note:In foreign countries it also happens that young people in rural places say that they want to make amps, e-mails will jump in once, in about a few years. Starting from studying electricity, parts, how to procure parts?
I am teaching in a poor English and Spanish at departure from 0 zero at all. Rich are relatively easy. I reply that I should buy this with this, I will reply whenever I do not understand
I promise, I will do a mouthful saying. In a few people a year, there is a person who is addicted to audio crucibles. People who only have a smartphone are serious. How do you teach? Very difficult
It can not be read by sending circuit diagrams etc, and there are various things. First of all, it is recommended that such people buy a PC, from there to the main subject.
