I think you're right. I'm surprised the 'pinch wheel' or capstan or
whatever it's called hasn't deteriorated yet. I have an old reel to reel
with a rotting rubber 'pinchroller?'. I don't know if any new old stock
is available anywhere.

They were built like tanks. I sold mine back in '90 or so for around $50.

Head on over to rec.antiques.radio+phono news group.Somebody there can
tell you where to buy a new pinchroller,or whatever it's called.

They have a lot of pics of stuff here. There isn't a Sx-690, but the 680
may be the same thing, sold in a different area, or through the "Grey
market"..

It's not a bad unit, if I remember correctly. Pretty high end in the
cheaper line up..

I bought 6 stereo receivers last summer at yard sales. Two of them
were perfect and the others had problems but were sort of working. The
most common problems we one of the final amps blown, a blown fet in
the fm rf amp, scratchy controls, and intermittent capacitors. The main
reason people got rid of them was updating to new digital equipment and
they had been in use since the 70s. As far as I know, Pioneer made
pretty good stuff and you might get lucky. There were so many of them
around, I didnt bother to fix them (average cost=$2). I would make sure
the speakers were working and not shorted and hook them up, power up
and hope for the best. Some of these receivers had poor AM sections and
you might have to play with an antenna. Many people want the latest and
best and throw out perfecly good analog equipment that still produce
cheerful sounds. I still use casettes and they sound pretty good to me.

The outputs are usually blown because someone shorted the speaker wires.
You can usually figure out that the finals and their drivers are damaged
with a DVM. Sometimes non-polar electrolytic capacitors in the feed-back
loop will be damaged. These will be in the 1 to 20 uF range. You might
also find a current steering diode or two blown in the higher output
amplifiers.

I only paid five dollars for the receiver and three dollars each for the
two Pioneer speakers at the Goodwill store yesterday.I could have hooked
up the speakers to the receiver at the store and plugged it into a wall
outlet tried it out right there,but I didn't think about it at the
time.Now,I need to find out (one of these days,if I ever get around to
it) what is loose and rattling around inside of the receiver.If
something is wrong with the receiver,I reckon I will keep it anyway.I am
not going to spend a lot of money on taking it somewhere around here for
repair.

Ask in sci.electronics.repair. I'm pretty sure I've seen mention there of
a place that has some NOS.

I've got an SX-850 that is in use all the time. 60 watts per channel
RMS...(2 channels). They are good units. Bought mine 2nd hand in Alaska
in about 1987. Pretty comparable to any transistor unit, not quite as
thrilling as my old Dynakit tube equipment, but that got lost.
