I'm no expert on motors, but an incorrect capacitor
value will not affect speed as far as I know.

AFAIK you need two phases 90 degrees apart for a
synchronous motor, and the capacitor is for phase
I've read if they are not 90 degrees you get more
vibration, but I don't really know.

Replacing the capacitor/capacitors seems like
a very good idea to me for an old turntable.

Well, I work in a motors company, but I'm not an expert either

It doesn't change the speed, but can do it with the torque, so the slip changes, so does (slightly) the speed.
What is beyond the speaker?

Don't trow money into sony or pioneer junk turntable. Buy or built a real turntable.
i used to have a "high end" pioneer record player. Lot of tics and pops.
finaly decide to buy a used Oracle Delphi 4. Result: the lp must have to be in really bad shape to hear noise with the music. It's even better than my cdp.

Thanks Daniel-A, but I can't throw in the towel just yet. I'm tinkerer & learning alot from these decks. I've come to the conclusion that it's worth messing around with these for now as I have nothing to lose if I wreck one of these. Maybe down the road I'll get into a higher end machine.

I will admit that the sony is a bit cheap in some respects (plastic base, not so heavy platter), but I haven't given up on it yet. I am learning quite a bit about setup & tweaking, even with this seemingly cheap deck. If I could find out what the proper compliance rating is (no manual), I could match up a resonably priced pickup. Right now I have a pickering TL-3 for which I do not know the specs, I have no idea if it's right for the arm. Mainly, this deck will be used with the computer for transfers to CD.

The pioneer is a well made deck with a good bearing. If I can get the speed right & get the arm set up well (or swap in a decent arm, Grace 707 or RB250), it should be adequate for my existing system. Again, learning quite a bit from experimenting with this table.

Well, the table has been completely disassembled & is awaiting a pulley that a friend is machining. This will mate to the maxon motor I plan to adapt to the original motor mounting plate. Then I can evaluate belt aligment & get the motor mounted. I also have a maxon motor controller that should be able to dial in the desired speeds.

Meanwhile, I obtained a grado green on ebay & I am breaking that in on my sony DD table. So far, it sounds great compared to any of the previous carts I have had around here. Eventually, I'll find an arm for the Pioneer (Grace 707?) & get it all back together.

Hello Everyone,
I have a Pioneer PLC-590 turntable with a Mission 774 tonearm mounted. The arm needs new cables for the counter weights. I have been thinking about finding someone who ties fishing fies to
make them. I don't have the arm's instructions anymore so I really
don't know the length it should be.
