I put here the original schematic that I used...with the following modifications: V1,2 V3,4=6N6P(russian) Ua=400V R2=18k/1w,R6=12k/1w,I also added a trim pot(20K) on the anode of V3,4 for simetry of the signal...now the most important part..I used one pair of GU50/channel,so the OT(output trafo) becames Raa=6k4 5000 windings of CuEm=0,25 and secondary 189 windings of 0,6CuEm you can see in the attachment...I used 28Cm2 instead of 24Cm2

All well and good, but you didnt show the real schematic yet, just a generic one...

Also, I am sure it will not play very well on top of your loudspeaker.

Data viitoare sa specifici in titlu ca amplificatorul este PP , ca sa nu mai piarda vremea cu subiectul tau......( into Romanian )
Next time you specify in the title as the amplifier is PP not to spend time with your subject ......

so..is there a problem? I don't think so...my subject was just like in the title....I wasn't refering to PP or SE...whoever is curious...is free to look...so...do you have a problem with that? I don't see something concret on this forum...so...until that...mind of your own buisness...vanity pisses me off....romanian vanity..I don't get rid of this...not even here...

I downloaded everything. All I saw was a 1955 Mullard schematic, a schematic from your final stage, without driver, and 4 PCB layouts. Now I do not know what Gimp saw, but am I supposed to trace the PCB's to see how is your circuit wired???
