World Audio single ended 4W questions

[a***@gmail.com]

Hello,
I have a possibility to buy one 6 years old World Audio DIY single ended
tube integrated amplifier. But the output tube is not there ! This
amplifier has three 6922 in the preamp section and one big valve in the
output section. Does anybody know what kind of valve it is ? Maybe
somebody has a schematic and description for this amplifier ?
Cheers, Tomek
PS You can mail me directly, if you like

I need a schematic for this amp . Does anyone have a copy that they could email me? Thank you !

I did a couple of articles on 6080 triode amps sometime back. A pair of 6080's in PP yielded an easy 30W at very low distortion. Looks like a copy of it is still here at-
