I'm new here. I hope I'm in the right place. I've read a few posts that seem applicable in the first few pages, but I haven't exhaustively searched the forum first. Correct me in my ways if necessary!
I've got a Technics SA-103 from my high school days, and it needs a little TLC. The pots and input selector switch are noisy. The FM stereo decoder does not want to kick in unless I fiddle with the stereo/mono push button switch a lot. And, as long as I will have it open, the lights on the tuning dial indicator have gone out.
I'm no stranger to electronics, have taken plenty of things apart, rebuilt a tube based jukebox amp or two, etc. But this being my baby (more sentimental than real value I'm sure), I want to adopt best practices for this one.
For cleaning the pots and switches, I was hoping to find a generally recommended best practices sticky post or something. Both the input selector and the volume knob really need my attention here, the others are not nearly as bad. What products should I use for the Pots? For the selector? Caig has such a variety of products but they don't seem to be telling me exactly which ones I need for this. Deoxit (which one?) followed by Fader Lube? Or is Fader Lube only for slide pots? How about the selector switch?
For the FM stereo problem, do I just need to make an adjustment? Or, is it likely I need to replace aging electrolytic caps? The one thing I have going for me is over the years, this unit has been powered on at least once a week or so, it's never sat on the shelf unused for any length of time.
Finally, how to find replacement lamps for the tuning slider? Two bulbs, was it white and green?
Thanks for any help!
