I picked up this free Rock-ola SuperSound jukebox the owner said it was from their family’s business back in the day but it had sat in their barn ever since and didn’t know if it worked. After getting it home and drilling the locks we discovered it was complete! Sadly no records where in it, but everything that made it a jukebox was there. It did come with a few bonus’ which included a free mouse nest, and around 2 dollars in quarters. After removing the mouse nest and vacuuming out the cabinet we plugged it in and it turned right on! Their was a few issues, the florescent bulb holders had bent so it wouldn’t hold them in and more importantly it wouldn’t move the griper arm without blowing the internal breaker. I removed the motors since they were geared so I could try to move the griper by hand which didn’t work so after a lot of WD-40 to break up the old grease and a bunch of new grease i was able to move it by hand finally. But after putting the motors back it was still blowing the breaker, not as much but still pretty often. I then decide to take the motors back out and tear them completely apart and rebuild them greasing everything up. Before I did that you could barely turn the shaft by hand however after the rebuild you could give it a spin by hand. After putting those motors back on it was working right or so I thought. I found that the right side was way quieter than the left but I decided to ignore that for now and focus on the cabinet itself, the one side was broken at the bottom, paint was missing on almost everything, and the SuperSound glass at the bottom had all its paint flaking off. So after getting it working I took it completely apart. after a couple rusted screws and broken off bolts I got the cabinet gutted. In the bottom compartment of the jukebox I found for some reason they didn’t paint it so all that wood had a thin layer of mold on all it. After cleaning and killing the mold I repainted the cabinet with white on the inside (it was slightly more yellow than white originally but im pretty sure that was from yellowing. After that I used some body filler to fix the broken bottom edge and after sanding that I removed the vinyl side pieces which wasn’t hard since they where almost completely off by themselves. I than repainted the cabinet in black, I made sure to tape off the model and serial number sticker and the Rock-ola logo on the back. I than had to repaint all the metal bits, first I had to remove all the rust which I did with a drill with a wire wheel I had to remove the rust from both handles, the four wheels, and the metal frames for all the surrounding off the front glass doors. On the selection screen there are translucent buttons with indented letters and numbers that originally had black paint in the indentations but almost all of that was gone from all the buttons so I decided to repaint those by just covering them in paint and then wiping it from the raised part of the buttons, this made the cabinet look way better and made the buttons easier to read. Then I went over the electronics mainly just to get an idea of how it worked and when I was going over the power supply I found a very swelled cap which I replaced. On the sides of the SuperSound cabinet there are coloured plastic little cylinders which aren’t their on SuperSound2 cabinets (keep that in mind) and I found that it was going to cost $50 to get bran-used ones on eBay which remember this cabinet was free. I found another complete SuperSound cabinet for $25 but the seller said it didn’t work and it sat outside so after buying that I switched the plastic cylinders to my restored cabinet. Well after I got it all back together I powered it on and put some records in it sounded just like it did before I did anything so at least I didn’t make it worse, I decided I needed to get some good records since the only 45’s I had where very beat up. After getting some good records they sounded good but the vocals where really low compared to the rest of the music so someone on a forum suggested that my jukebox was out of phase so after swapping two of the wires on the cartridge it sounded great but as I find later not as good as it can. So what about the rest of the stuff from the parts cabinet? Well the cabinet while its restorable it would take an insane amount of wood hardener, body filler, and a ton of sanding because the cabinet is swelled up a bit from setting outside. Well in an earlier project I took a stripped SuperSound2 cabinet and made it into a Bluetooth jukebox, and remember I said the SuperSound2 doesn’t have those plastic cylinders so I wouldn’t need those anyway to make it complete so I decided to take all the electronics from the parts jukebox and put them in the SuperSound2 cabinet. The only issue, I hadn’t tested the parts jukebox because the cord was cut so the flippy flop arm was stuck even worse than the free jukebox’s arm but after even more oil, grease and cleaning I got it moving even better than the free jukebox. after putting it all together I went to turn it on and… two lights didn’t light up on the power supply showing it didn’t have the -28v and the +25v so I opened up the power supply and that same cap that was swelled on the other jukebox was not only swelled, it was blown, and a resistor was also very blown, when removing the blown cap I accidentally removed the cap right beside it so I tested it and it tested not the best but also still usable so I put it back without thinking. So after replacing the blown cap and resistor and put the jukebox back together powered it on and it still didn’t have those lights and then the power supply started smoking so I quickly shut off the power and opened it up to find my brand new resistor was blown. After checking around on the board I found two bad transistors and after replacing both of those and the resistor again I put it back together powered it up and boom it didn’t work and then after a few seconds I hear POP. I shut down the power again and take the power supply apart again to find that cap I accidentally removed had blown but when I was looking at it I realized I messed up and managed to put the cap on backwards. After replacing that and puting it back In the jukebox It still didn’t fix it so I took that board from the other jukebox’s power supply and put it in and when I powered it up on my work bench and it worked so I went around and found a bad diode on the board so now while waiting for that to come in I decided to put the known working power supply in the jukebox to test everything else and when I plugged it all in inside the jukebox and powered it on I found I had no +25v again. So I swapped the motherboard from the working jukebox in to test the rest of the jukebox. After I swapped motherboards it all booted up nicely however the amp I was thinking wasn’t working because the other jukebox had a hum I was blaming on the florescent lights but when I put a record in and it flipped it all around it started playing perfectly no hum nothing just sounded great. I did find that the jukebox couldn’t get to the “100” section  and was stuck in the “200” section basically it could only play the B side of records but I found the mechanism that swaps which way the record turns during the flipping was stuck and after breaking it free it was able to move to the “100” section again, however it has already become stuck again so I figure I need to take that mechanism apart and give it a good clean and oil it up. Now back to the motherboard, this motherboard consists of two boards, the CPU board and the memory board, I decided to figure out which board the issue was on I put the good cpu board with the “bad” memory board and that worked just fine so I knew it had to do with the CPU board. After looking all over it I didn’t see anything clearly blown. The free jukebox came with some really cool original paperwork which included a parts catalog, control unit manual, and a wiring diagram for everything, well I decided to pull out the MASSIVE wiring diagram and after a bunch of wire chasing I found that the first thing in the 25v line was a little tantalum cap which I’ve never heard or. After removing the cap I noticed it had a crack in it and was darkened around the crack and sure enough when I put it on the cap tester it tested completely open. So to make sure that was the only issue I took the same cap off the working motherboard and put it on and it didn’t work.. then I noticed that there was a + symbol and then I realized tantalum caps are directional like electrolytic caps. After swapping the caps direction I put the board in the machine and it booted up and was fully functional. Now I’m still waiting on the diode for the power supply and the cap for the motherboard, but due to the current pandemic shipping is rather slow. When those come in I’ll have two fully functional SuperSound jukebox’s however because I know this amp sounds so much better I’ll have to do some fault-finding but I have a feeling it’s a filter cap. About the parts cabinet, I believe I’ll just remove everything that isn’t the swelled wood and then maybe post it for free and see if anyone wants it to restore. Here are before and after photos
