On a Seeburg Model 100A, would the absence of the 2050 tube in the Wired Selection Receiver prevent write-in to the solenoid assembly? I am not using wall boxes.
My memory was thinking that the 2050 tube was only needed if wall boxes were used. Looking at the schematic, it seems the 2050 tube is always needed on this model - and I don't have one, and my solenoid assembly does not get energized for write-ins. Everything else is working.
Am I correct or do I need to follow a different path to solve my problem?

No, it would have no effect on selections made from the jukebox itself. The 2050 is only in the circuit for the wallboxes. It's a pulse shaper andamplifier. (Early form of serial data transmission.)

Thanks, David!
I've now got the electrical selector located in the rear of the box. It will be easier to troubleshoot the circuit this way!
