The Parts Are Rolling in for the Rock-Ola

I had to order many of my new components through eBay, mostly because I found that the local electronics suppliers charge way too much for small parts in some cases. I'd love to buy locally instead of overseas, but I blame that on the local merchants. I have to wait a lot longer for things to arrive, but the time I wait patiently for parts still pays off in the long run.

Anyway, this was not a rant about economics so I will move on. I replaced the obvious parts in the power supply and was able to put it back in the Rock-Ola. I suspect that the caps I replaced there will affect the bad humming sound I was getting whenever the audio kicked in to play a record. I also recapped about half of the amplifier, again only replacing the visually obvious parts first. I did poke around and test other components and really only found a bad diode otherwise that may also contribute to the hum probably I was noticing.

So, the unit powers up again with no issues but part of the electronic selector circuits are still located in the amplifier that I haven't put back in yet. I greased or oiled as many mechanical parts as I could and those parts are moving much smoother. I even solved a record retrieval issue the unit was having just by updating the grease.

So hopefully I get the last of my parts this week and can put this machine back together. And if I am satisfied with the audio quality and overall performance of the machine, then I will look at the cosmetic issues like chipped paint, scratches and such.

But so far, so good. This is very exciting!
