Hello. Last weekend I stopped by an estate sale and spied a lovely Sony PS-1800 turntable, but alas the tag had already been pulled on it. After scanning the sale for a half-hour or so, my only purchase was a $7 sleeve of 70's baseball cards of dubious value (turned out it had a lot of nice cards, including five Tom Glavine rookie Topps!). Felling a little disappointed as I walked out, I noticed the fellow that grabbed the Sony happened to be loading his purchases into his truck. As I lingered, his receipt was visible and I saw he grabbed it for a puny $20. On a whim I asked if he wanted to double his money and he said yes! So off I went with the Sony. OK - enough backstory. Down to the issue at hand. It's a very nice table, and rather rare apparently. Unfortunately I can't get it 100% operational. It is turned on by flipping a toggle lever - to the right for 33 and left for 45. The middle position is "off". When I flip the toggle to either side, the lever won't catch and hold. When I release the lever, the tonearm lifts and returns and the machine is off. If I keep the lever in place with my hand, the table operates fine - the strobe is lit and the cool red "reject/off" light on the front of the plinth is lit. But as soon as I let up on the toggle - it flips back to center, the arm returns and everything turns off. From previous research regarding this table on AK, I see that it seems to be operated with magnets "magnetodiode" - something I'm not very familiar with. My basic question is - am I dealing with a strictly mechanical issue like a worn or broken piece that keeps the toggle from catching, or is some type of problem with these magnets or a sensor keeping the mechanical switch from grabbing? Any insight is appreciated. I am going to dig into it later today and being forearmed might help me. Thanks as always.
