Thanks Terry. I get 650 ohms between pins 2 & 3 on 41. I forgot to mention in my previous post, that the white wire from the output transformer terminal is connect to the plate pin (pin 2) and the black wire to pin 3 on 41. the green wire is to field coil connection. I replaced the two electro caps of C31 (the 10 and 12) and now get 240 vdc on pins 2 and 3 tube 41. I think I should also looks at the 4 of C30 now too. Still have non-tunable hum from speaker.-- Andy
