Hi everyone !

I`m kind of new in the wonderful world of tube audio amplifier... but as summer come, I would like to build a 2 channel x 25 Weff hifi audio amplifier. I got valve amplifier book of Morgan Jones, so you can make some reference in it....
Got just the thing for ya! If interested, send me an e-mail so's I can send all the details. I'd attach, but there's not enough room for this. so I'll have to e-mail it.

In the mean time, see Here to get a good idea of what I designed and built. After getting this one tweaked out, the sound is excellent. Do keep in mind that the 807/6L6/1624/1625/6BG6 are all identical, and the circuit won't require any modification for using 6L6s rather than 807s.

I noticed this one very late, so just to confirm from a lot of experience with basic p.p. 6L6 amps:

6L6GC will give 40W in UL with a good opt, but I found the cathodyne phase splitter to be somewhat stressed delivering the odd 150Vpp required. I used pentode input directly coupled to LTP ECC81 or such - well known old circuit.

Good luck!
