Philco model 610
#10

Terry,
Thanks for helping me and plz understand I am still very new at this. I went out today and rechecked the speaker, the field coil and my rewiring. All seems good and correct. I think I understand the schematics really well but I struggle with trouble shooting and terminology. When you say to measure across the second filter cap do you mean from one end of the cap to the other or take measurements at each end to the chassis. Don't laugh or say rookie lol. End to end is -400v. Measuring at each end to chassis is 355v at pos end and -24v at neg end. Also You are talking about number 55 8mf filter cap aren't you.

Also I will list the pin voltages for the 80, 6A7 and the 42. The 80 tube voltages are pin 1 to chassis 385v, pin 4 to chassis 381v, pin 3-4 725 vac. The 6a7 pin 1 - 7.3v, pin 2 - 225v, pin 3 - 57v, pin 4 - 103v, pin 5 - -123v, pin 6 - .016v, pin 7 - .012. The 42 tube pin 1 - 7.2v, pin 2 - 355v, pin 3 - 354v, pin 4 - -24v, pin 5 - .3v, pin 6 - .010v.

I also read a thread on another 610 that had similar voltages on the 6a7 and he had a problem with the 32k resistor. Just to let you know I did recap and change out all resistors. I went back and checked the resistor values in the set and the only one that is not real close is the 3/4 meg that connects to part 57 (which ohmed out good too). It is reading 710K instead of 750k.
