[Jukebox-list] Seeburg M100A Buzzing

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
