[Jukebox-list] Re: SPS-160 DCC3 "Play Control" Question

[Dwaine Maggart]

Thanks everyone. Using the provided info, and now better understanding how
the Add/Subtract mechanism works, and why, I was able to clean the
Add/Subtract solenoid plungers, which were dirty and sticky, and adjust the
2E2 contacts as Ron described, and burnish and Deoxit the 8M1 and 8M2
contacts on the "Play Control Subtract Switch" and now it is all working as
described. And yes Ron, it appears the .01 cap across the 2E2 contacts was
cut out at some point. There is still a bit of the old leads on the contact
solder points. Is this really a 14KV cap??? It appears to be 1.4KV on the
DCC3 Chassis schematic. I need to replace it before the contacts weld again.
I wonder why someone would have removed it?

I've loaded it up with records, and it seems like all the selections (so
far) are working. 80 records is a lot of selections! Seems like a lot more
than the M100B.

I'll try to put a few pics up on the jukeboxpictures group.

Thanks again for all the help!

Regards,
Dwaine
