Thanks everyone. I went to electronics school back in the eighties. I worked for a few years repairing calculators, then left electronics for a great job offer not in electronics. I have forgotten more that I ever learned! I apreciate the help. I'm retired and thought it would be fun to pick up this hobby. The bluetooth module is this one:https://www.retroradioshop.com/collections/diy-bluetooth-kits/products/retro-vintage-or-antique-radio-bluetooth-upgrade-kit I purchased the radio off eBay. I was told the paper capacitors have been replaced. I see it has 2 new capacitors, that's all I see that looks new besides the power cord. I think I have it figured out, but I'm worried since Gary says "all paper and electrolytic caps must be replaced" and I only see the 2 new caps. I'll probably go ahead and see if I can get this module installed and see what kind of performance I get and go from there. Advice is always apreciated!
