output
I'll have to check on the b+ fore the 45. It may be too high. I do have a cathode bias resistor, the schem is drawn wrong. As I said in a earlier post in this thread, the cap and resistor are actually below the pot not above it. Guess I had better correct the schem and repost it.
Input
This came up the first time I breadboarded this amp. I think Tre' brought it up. The preamp I am using has a single 26 tube so we decided that made things ok again.
Power supply
Are you saying I should take out the cap and resistor between the 26 and the 26 and 45 and make it direct coupled?
