Tom, thanks for looking. I'm about ready to chalk it up to an undocumented change.? I found another anomaly while working on the chassis.? There is a large transfomer on the bottom of the unit that has "T-12" printed on it.? My radio has a 10 uF electrolytic going between the leads on this guy.? No mention of that part anywhere that I can find.? Does your FT-101B have this part?? I had an extra 10 uF so went ahead and replaced it.?
As to the challenge, it was certainly a mixed bag. I would not have attempted it without a desoldering tool.? I tested the radio after every board or two.? Most of the boards were straightforward. Getting at the caps on PB-1180 (the one in the metal box) was a challenge; and the caps hiding under, and sharing solder joints with, wires and other components on the chassis took some thought.? ?The next project is the big filter caps? I haven't come across any description how to best change these out.? A project for sure.? Good luck with your radio!
