[Jukebox-list] Seeburg TSU5 question

[Ron Rich]

Chris,
  First of all, what the heck is an "album unit"? Second, the "solenoids buzzing" is bad. If you do not have an RCSU, I suspect that the "scan control solenoid" is what you are hearing--check the adjustment per the service manual--hint-- be sure that the .01 cap is still connected across the contact points. As for your selection problems, sounds like you may have a resistor out of tolerance. Most likely suspects are the 56k 2w and or, the one in the pulse amp that connects to the .05 cap, that you changed. Ron Rich

  Hi all-

Finally getting to put together my Seeburg AY. The amp is recapped and
sounding great, but I'm still having problems with the selector unit.

I have recapped this as well-and at least I don't feel so bad that it didn't
work right away. It was only good for 1 or 2 selections before the rebuild.

It does the scan twice and stop. I went through the troubleshooting and got
to section "M" where you jumper A & B while scanning to make it select. It
does, and it ejects properly too.

What I have noticed is that I also hear the solenoids buzzing when it hits
the home position. I can make this stop by pulling the J501 mechanism plug.

The 12AX7 on the pulse amp is fresh and known working, and the OA2's are
also purple. I have also disconnected the album unit.

I'm suspecting I have maybe a couple of problems. Any thoughts where to
turn first?

Thanks in advance-
Chris
