I am still working over some big sweep monoblocks, but I'm going nuts with my SS amp and no tube amp. This chassis is made from 12ga steel, and lots of venting.
I think I can pull this off with all the tubes inside the chassis. I'm planning on running UL at ~450VDC B+. The 6550 datasheet says at max signal, two 6550 tubes needs 275mA for 100W output. I mostly see 6550 and KT88 amps rated at 70W output. Do I really need 275mA per pair of tubes?
See anything wrong with this layout?
Also, I always use big 2W pots for bias. I know it's way overkill. What wattage is acceptable for these pots? I'm trying up keep the circuitry small.
Thanks!
