Fairbanks Morse model 91
#7

Looks like there is a 4mfd, a 100 mfd, and a cardboard can with a 16 and a 30 mfd in it.
Someone replaced the double one with a 16 and an 8 mfd.
Looks like they wired the positive ends of the 16 and the 8 together and connected them to the center tap of the 100 mfd.
Then both the negatives were connected to chassis ground.
This is not what the schematics say, as far as I can tell.
Can anyone draw me a readable diagram of where the pos. and neg. ends of these caps are supposed to be wired originally?
I am having trouble with the provided schematics.
They don't even give polarity on the electrolitic caps.
If I had your email address, I could supply you with a couple pics that might help.
I don't have much luck posting pictures on here.Guess I could have my kid teach me, but he is never home.
Anyone interested in helping out?
This is a rare radio, and I don't want to mess it up.
Thanks guy's and have a great weekend.
