Murf, I am attaching a link for the schematic for others. This is one of three versions, not certain which one you have for the 91. I can't see that a 100mfd cap would be appropriate anywhere on a radio of this age.
As for posting, this has got a lot easier with Ron's effort. Download your pictures to your desk top from your camera. Label them so you know what they are. Type your thread and go to the bottom and look for the attaching information. I use photobucket and have learned how to use it but the Phorum has an easier method.
Regards, Jerry

Murf, this is an edit. I looked a little closer and you have items 30 and 31 as a 16mfd and 30 mfd negative going to the centertap of the transformer for the 30mfd and the negative for 31 going to chassis. You have cap 27 a 4mfd with negative to ground. Confusing me is item #4 on the schematic being listed as a 100 mfd. Just doesn't seem right to my limited understanding of radios. And no Murf, 30 and 31 should have separate grounds and go to different locations as indicated.
