Sorry about being so long in replying. My model is 8106, and that is what the sticker inside the cabinet says. My Sams 389-3 has it listed by the chassis, which is 528.50124. Both numbers are also on the back of the set.
I did make a little progress. R38, and 8200 ohm @ 2W was bad. I had replaced it earlier, but during a bench test, I had walked out of the room. When I got back the horiz was way off sync and squeeling, and that resistor was frying. It still checked good, so I left it in place not realizing that's when those horiz problems started. I put a new on in, and that kept the horiz from drifting ever few seconds.
It is still touchy and keeps losing sync, but I just have to bump the hold to correct it. Sound has also gotten weak. I tried doing an alignment on the audio using the instructions in the Sams, and that's didn't help. I then noticed when I would stick the alignment tool in the top of A8 (L15) the sound would get louder for a brief second.
A7/8 (L15) is a 4.5MC trap and also a Sound IF. It has two 33pf capacitors in parallel with it. I'm thinking maybe these have gone bad, so I've got some on order. The bottom slug on the coil is also stuck. I checked with Moyers, but so far they haven't found one yet.
My Sams only list the Silvertone number for the coil 10-120-1. Haven't been able to find a cross reference for that number yet.
