replacing 38-116 code 125 RF deck capacitors
#1

I changed out all the caps but one, which I saved for last (part 7). This was the only hard one. It was buried behind the antenna coils at the rear of the deck. I could barely see it in there. It was so hard to get to, I decided to leave it in place and just cut one side of it and wire in a new one somewhere else.

I could not see how to take it out without removing the deck and that was "over my head" at this point, too many wires and parts to disconnect. I was able to see one end of it from the top through the hole where the tuning cap goes through. Luckily, I found a 150w soldering iron at a year sales two weeks ago. Never needed on before. My 25w worked fine for several years of restoring.

I unsoldered the grounds with the new iron, unbolt the two front bolts that hold it in place, and then I was able to push the tuning mechanism forward just enough to remove the tuning cap. I was able to cut the end of part 7 and move it aside. I then added a new.05 with one end through the hole and soldered where the old one was and then wired the other side of it to ground on the top of the chassis through that same hole. Now when I have some time to review my repairs, I'll bring it up on the variac and see if it plays. All out of tolerance resistors were also replaced as well as rebuilding the three light fixtures.

How have you replaced this hard to reach cap? Is there an easier way I could not see? I have another 38-116 to restore (this one is for my cousin) and I would to know an easier way if there is one.

Thanks,
Steve
