Philco model 610

Yes. It can.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Keith, I'm sorry that I didn't get to you back by Saturday. Here are the pin resistances like you asked.

80 Tube
pin 1 86.8
pin 2 .404
pin 3 .414
pin 4 86.8

6A7 Tube
pin 1 .7
pin 2 76.9
pin 3 50.5
pin 4 110.3
Pin 5 10.16 Differs quite a lot from yours
pin 6 .6
Pin 7 .6

78 Tube
pin 1 .6
pin 2 nothing because I have the speaker tore down right now
pin 3 51.5
pin 4 22.2
pin 5 .6
pin 6 .6

75 Tube
pin 1 .7
pin 2 same as above
pin 3 .735
pin 4 .588
pin 5 .5
pin 6 .6

42 Tube
pin 1 .7
pin 2 same as above
pin 3 same as above
pin 4 .541
pin 5 .6
pin 6 .7

The reason that I tore the speaker down is because of the posts that Morzh did. I am pretty sure that my problem is here anyway. I forgot to get those resistances before I did that though. While I have it tore down I will reinstall yellow wires to the speaker to minimize confusion. I am pretty sure of my wiring though. I think I have a short inside the field coil and hope I get lucky it is on top. The resistance keeps changing each time I handle it. Just so you know the resistance went to 6.39k when I disconnected one lead so it went up as Morzh said. Thanks for your help for a newbie.
