ISO EL84 SE Schematic

Posted on April 26, 2000 at 06:34:54

I have some parts to build an EL84-powered SE power amp and am looking
for a schematic. Want to have a triode/pentode mode option. Can anyone point me in the direction of a good schematic? Thanks!

Here are a few.

You could try asking Steve Deckert at Decware if he sells the schematic/plans for his Zen amp. I think that at one time is used an EL84 single ended.

can't make it any easier than this: Steve has schematics and even detailed assembly instructions (I mean REALLY detailed with photos!!!!!) at the Decware site. He will also sell you output transformers if you ask nice.....

I bought an old SE 7189 amp mainly for the transformers in the interest of building a new SE amp.

Can I blindly use the power/output transformers and build a EL84 design? Assuming of course they use the same rectifier/preamp tubes?

And if I do this, can I use the 7189 tubes or would I need to get some el84s?

Some how I doubt life could be so simple and I realize this wont be a true SET but I am poor and this seems like a good place to start.

Thanks for any help
Dave

I don't see why not as the 7189 is a substitute for the EL84. Go for it and have fun.
