807 tube amp, any ideas?
Been looking at building a hi-fi amp with 807's mostly because i have stacks of the things and they look cool, especially with their blue glow.
Probably would set up in class AB/AB1 configuration at 400V, ultra linear and cathode bias.
I know there is some debate about running the screen voltages over 400V on the 807, but I know they run perfectly OK at 400V without any issues and I have built a 100W marshall clone amp using them at 400V and its poking out over 160W from a quad.
AWA Radiotron in Australia even released a technical bulletin regarding the screen voltages in this regard too supporting this.
Anyway, I was looking at using 6J7 / EF37A as the driver and a 6SL7 as the phase inverter.
Any other suggestions? Ive never built an amp from scratch before, but am looking at similar designs to the Mullard 5-10 amp.
I expect I should get a good 25-30W per channel from a push pull pair of 807's
