Hello all,
I am working my way through my 37-116X, slowly going through the electronic restoration. I have replaced all the wax/paper caps and OT resistors in the power unit, and most of the IF unit. I have powered up and the radio is operating, as I replace a little and check, as I go. I really didn't want to dig into the RF chassis, but it must be done. I have now removed the RF sub-chassis, and am replacing what wax/paper caps that I can get to. Those that I have replaced have been very leaky, as measured on my Tel-Ohmike. There are two caps that are really buried within the band switch. I am scratching my head, trying to figure out how to go about replacing them. I am afraid to move too much around, afraid of breaking something, or causing more damages. Any tips or tricks as to how to go about replacing those two down in the band switch? I was thinking of some how attaching the switch contact end at another location, and mounting the caps outside the switch some how. But, so far, have not found a way to get into them. I have two chassis at my disposal, but would rather not have to dig into the other one to salvage parts if I don't need to. I am wondering just how important it is to replace these caps. I am thinking, since it works, maybe I should let sleeping dogs lie? This radio is for me, and not for someone else. Nor do I intend to sell.
Thanks for looking.
