So this morning I aligned the set. The IF was off significantly, but not now. On band C, I was not able to bring the 15 MC signal down to 15 on the dial as I ran out of thread on the screw - as it is, the oscillator screw is just about all the way out and 15 MC is still coming in at about 15.5 on the dial. I guess that will have to do. AM (band A) aligned up nicely. No adjustments for band B.
I made a slight mod, temporarily, to the tone control circuit. I disconnected the end of C33 from the tone control. The radio no longer squeals as a result.
Once I find an apporpriate tone control and install it, this radio will be finished.
Oh, and I forgot to mention - the power transformer is not overheating, even though it had obviously leaked out a lot of wax when I acquired the set. Someone must have kept playing it on failing electrolytic capacitors. Fortunately it seems to be OK. The Solen film caps it now has in place of the electrolytics should last a long time.
