I just pulled the 2 chassis' out of my 37-690 to get a good look at them, and I find that I have what appears to be a 38-690 chassis in my 37. There are 6 tubes on the power chassis instead of 7, and 14 tubes on the receiver chassis instead of 13.
The tube layout on both chassis' match the 38-690.
My question to you is did Philco possibly run out of the 37-690 chassis and substitute the 38-690 chassis?
All of the caps and resistors are original with the exception of 2 lytics, so this hasn't seen much service.
I'm fine with this, just trying to understand.
Any help you can provide is appreciated!
Thanks
Chris
