I just wanted to say thank you to everyone that has helped me in my journey restoring my Seeburg HF100r. For many years I have restored vintage wedgehead style pinball machines and always wanted a jukebox and always a Seeburg. I finally had the opportunity to pick up this 100R that was not working well, to not at all and needs a great deal of esthetic restoration. After re-capping the receiver and now the Amp (Wow what a sound difference), stripping down the entire mechanism and rebuilding it from the ground up, cleaning and readjusting as I went.

I now have the unit fully function... 99% , I have been able to pickup some of the physical pieces that were missing from the cabinet, glass fluted panels, waterfall grille, etc... So now the restoration kicks into high gear. I am going to start stripping down the entire machine and rebuild the cabinet, painting, new veneer side walls, grill covering, etc...

All the years of pinball restoration paid off, recapped the amp in about 4 hours and stripped down and cleaned the pinbank in about the same amount of time.

Thank you again, especially Rob and Ron. Chasing my 25V issue to the mech was physically draining but all worth it now.

FYI.. The 1% that I have an issue with is, sometimes and very infrequently, when a record is picked up it will not cancel the pin. I am talking probably 1 out of 50+ records and it is not always the same record or side, very random. But more tweaking once I put everything back together should resolve that a bit better....

Ron,
Glad you "got it"--BUT--what didja find ??
Two reasons for the 1 % problem--Frog "alignment", and C-SC ( got it right, this time ), contact adjustments.
Frog alignment especially, on R-J models, is subject to being compromised if phono has --EVER--been, moved on it's back, without being properly bolted down !

Ron, you are most welcome.

Well I spend a bit more time on the issue with the cancel coils not kicking the pins back. I have gone through the SC & C contacts and at least for now are properly set. Here is still the issue, the A side coil (one towards the rear of the machine) you will see a slight movement of the plunger no matter what end of the units it is on, 50/50 if it resets it completely or halfway or not at all, even when not at all, the plunger will still move (fyi...the pins are free to move, cleaned the pin bank weeks ago). The B side will reset the pin every time, ran 50 songs and 50 out of 50 worked perfectly fine, the A side was 28 cleared, 5 half way reset and 16 not at all out of 50.

So it seems that the contacts for SC & C are working as the B side works fine and even if side A does not reset the pin I do see the plunger move. So the question then is this an electrical issue or a failure of a cancel coin?

I did replace both plungers and springs and oiled them both, they manually feel the same with no real resistance, very smooth. I assume, this also means the Contact Block alignment is correct as well.

Ron,
First--remove any "oil" or "lubricants"from these coils ( and all others too ! as they should be clean and dry). I have found that problem to be the fact that the brass tube has moved inside the coil wire housing, itself. Look at the two cancel coils, and I think you will see what I am saying--to fix this, simply spread a little glue on the outside of the tube, and push it back into the coil housing. That should restore a "full stroke" to the plunger--if not, that coil must be replaced.

It is the coil... The brass tube is fine and has not moved. The fraction of oil was removed and cleaned out of the tube and off the plunger, still the same problem. I will order a new coil.
