Seeburg M100A Question
by Jim McClave 06 Apr '24

06 Apr '24

The A that Ive been working on with the loud buzzing noise seems like the mechanism is stuck. Its been converted to 33 speed. Should I still be able to turn the turntable hub by hand with power off to get it to cycle?

Found 3 saddle clips on the numeric board loose. The rivet / retainer that secured it to the board is missing. So I’m open to suggestions on how to secure it back to the board without hopefully having to remove the board

I have a customer who owns a model B Seeburg and has the opportunity to purchase a Custom Unit. The seller says everything is there except the amp. Never having any exposure to this model I want to know which amplifier was paired with it and would he be restricted to that amp or could a substitute be used? Thanks Rick

Loud buzzing as soon as you turn it on. The> mech wont move, and the turntable sits and spins. wont reject. Jim The machine will operate fine without the 2050 tube. It's only needed whenyou use wallboxes. I had a problem with mine long ago where the coil openedon the selection timing relay. This caused the credit solenoid to stay activatedand it did make a very loud buzzing noise. So as you know, the first step is tosee what's buzzing and fix that, so the machine can be put in a known point inthe play cycle. The fact that the buzzing starts as soon as the machine is turnedon indicates it's coming from an electro-mechanical rather than audio source.

This is a bummer juke to work on. someone else has been it a few years ago. I have discovered: 2050 tube missing, reject button , 2 wires pulled out of plug and each wire attached to the terminals of the visible fuse on the bottom of the wsr, Large plug that was supposed to go to the credit unit was plugged into 6sl7 socket on the amp. 6sl7 tube is now missing. Mech sits and spins, wont move or reject. Jim

Still working on the loud buzzing noise problem on the A. Cant really tell if the noise is coming out of the speaker or somewhere else. Is it ok to temporarily disconnect the speaker plug without damaging anything else? I know B+ goes thru the field coil. Jim
