Dear Sir, Has anyone got a schematic for a EL84 OTL Amp output Impedance does not matter. Thx. Peter

I don't think you'll be able to find a EL84 OTL schematics, because this tube is too weak for that. Is there a reason that it has to be this one?

Dear Sir,I have about 20 of those tubes(EL84) I would like to use them in a OTL type circuit No output transformer.

You compare the operating current of these tubes and the current required by your speakers. Something can be done for headphones, but no more.

I see. Well, if you insist, then most probably you'll have to modify an existing schematic, as EL84 is not being used in OTLs. Also, With 20 EL84 you'll get around 10-20W in OTL if you want to keep a low distortion. It will be hot as hell also, as each EL84 takes 5W just for heaters. Fun project, but not an easy one, nor practical.

Thx for the Advice.You are right.

No worries. Still, EL84 is a great tube, so if you have sensitive speakers then a classic PP, or PPP amplifier will sound great!
