Hi - I have 2 concerns - I would be grateful for any advice
A) V3 Voltages seem too low
and I am getting a crackling when amp has been on for > 30 minutes on both channels.
B+ 340, Mains 117, all other voltages are correct (within 5% or so)
V3 - seems odd that the offending pins are all about 20-30 volts lower than expected
1-203 (220)
2- 32 (52)
3- 70 (75)
6- 193 (217)
7-30 (62)
8-70 (75)
I have done the following:
1) retraced and checked continuity of all amp connections, including jumpers under the board
2) switch V3 - same voltages
3) rechecked all cap values and measured resistors for duds
Is this ok? If not, any ideas? The close-up is V3.
B) 6V6 voltages
One of my 6V6's won't get hot/glow in either socket. I took the same steps as above...maybe a faulty tube but what voltages should I expect for 6V6? There weren't any in the manual.

Thanks - best amp ever BTW.
