OK that wrong resistor has been replaced with a combination
procuding about 31.5K = close enough for a 33K.
I also found that the 6DE7 tube was DEAD. Not surprising after
forcing so much current through it. I have another tube in there
now, and guess what?
It sounds great - even with an AMPLIFIED D104, hi hi!
See you all on CW or AM soon!
