Quick update guys - After swapping out a few tubes, one was weak. However, I've gotten to the bottom of a bigger issue. The reason the volume seemed a little low is that after rechecking the coils again, I found a break in the outside coil of the first detector transformer (#7). Only the first 2 winds were deteriorated, but I'm guessing it's time for my first rewind. I took a high-res pic and counted 95 turns. Anyone know what gauge wire is used ? Can a heavier gauge wire be used with a variation in the number of turns? thanks-
