Hi Ron, Hope all is well. I have a question I’ve been working on Seeburg’s for many years. I am a 30 year experienced electrician as well. But this one kind of puzzles me. So when I leave the USC-1 powered on for a good 45 minutes It will start to play normal pick up all the records no issue. I have rebuilt and recapped everything. But once I first power up let’s see if I left it in the off position for about 30 minutes and then won’t pick up the records it will just scan but when it starts to pick up the records once it does about 45 minutes later it does remember all the selections. I’m thinking somewhere I have a leaky capacitor still but I don’t know where it would be I change mostly all of them any help would be greatly appreciated. I was told it’s possibly a transistor The 2 that are on the DCC-1 left & right of the test strip. All the voltages are good on the test strip. Let me know what you think thank you

Do you have a copy of my "MicroLog Trouble Shooting Guide" ? Do you have a copy of the Service Manual I would suspect the 7M1, or 3M1 contacts long prior to suspecting those two transistors ! Ron Rich
