I recently acquired a Technics SA-600 for the right price (free) from a friend who was downsizing to move out of state. He was the original owner but it had been in unprotected attic storage for many years including during a roof tear-off and replacement so it looked pretty rough. I removed the covers and blew all the dust and debris from the inside. I cleaned the circuit boards and wiring with isopropyl alcohol and a cheap paint brush. I cleaned all pots and switches with De-Oxit 5. After drying out I powered it up and it appears to function well. I ran a CD player through the Aux channel and it sounded nice, no scratchiness or other odd sounds. The AM and FM tuners seem to function as well. I haven't yet tried the phono input but hope it's good as well. Cosmetically, it cleaned up well and I like its looks.
The only non-functional piece is the balance control. My buddy told me the pot had gone bad many years ago. He replaced it with some generic pot (just so he could have a post to mount the knob) and hard-wired it so the balance is zeroed out and the pot does nothing. I'd like to replace the pot with an original or suitable replacement but am having some difficulty finding the correct value and part number.
I can't seem to find a service manual (or even specs) for the SA-600. I found manuals for SA-500 and SA-700 on Hifi Engine but no luck on the SA-600. It appears that the SA-600 is more similar to the SA-500 than the SA-700 but I'm not sure. The SA-500 manual shows the balance control pot to be 200K ohms while the SA-700 shows a value of 250K.
Does anyone have a service manual for the SA-600 they would be willing to share? If not, any info on the correct value for the balance control pot would be sufficient. Also, if anyone happens to know of a source for a replacement pot or happens to have one they'd be willing to part with I'd be grateful. Specs would be great as well.
I'd love to get this unit fully functional and put it into service. I know it would be fine with the non-functional balance control but that would drive me crazy every time I looked at it.
Thanks in advance for any help anyone can provide,
Joe
