Today was SMC1 day. I propped the upper lid up with a pipe and replaced the gas springs made by Suspa. Incredibly Suspa is still in business and replacement springs can be ordered directly from Suspa. Seeburg used 120 pound springs. I use 90 pound. These hold the lid up with no problem and more importantly allow the lid to gently close. The original 120 pounders can take quite a tug downward to get closed. I broke the back out of an SMC3 that had just been finished closing the lid for the first time after installing new 120 pounders. Made me sick. These cabinets are made of cheap particle board with practically no support. Just to finish the story I did get the SMC3 repaired using a very innovative fix with a lot of metal bolted in for side-to-back support. The part number for the 90 pound springs is C16-24190. These are direct bolt-in.
With the mechanism serviced and the amplifier making noise it is time to see what I have. The PCC had been tested in the prior SMC and works. I removed the CPA unit. Or, Collection/Play/Audit Microcomputer Memory Bank. Quite a mouthful for the piece with all the service switches. It also has a small automatic reject board that gets inspection and a cap replaced. I’m not sure why but I’ve never seen one of these CPA’s that has a clean top and this one was no exception. I pushed the top connector through, taped off the hole from underneath, sanded the top down and sprayed with silver metallic hammer tone spray paint and remounted everything.
The MCU from this juke works. I had to replace one of the voltage regulators in the MCU case and the battery holder which is usually corroded from the batteries being left in them for umpteen years. These will operate without batteries which are used to keep coin audit and pop meter data in memory for the operator to use. I am fortunate there was no battery corrosion on the boards. Just some on the metal case which got cleaned off and repainted.I also use a smaller AA battery holder setup rather than three larger, heavier C batteries.
I installed the MCU held my breath and turned it on. The mech scanned and the MCU inititated. I made several selections and shut it off. Today was just to get to this point. I have a working jukebox. I’ll fine tune it and finish the cosmetics as I can or when I find a chunk of time.
