The good tonearm with wires.
Installed in Black PS-4300, ready to be soldered in.
The auto function is working now! needed some oil on the sticky levers.:thmbsp:
Thanks,

Could you give me any tips/advice on soldering those tiny wires coming from the tonearm? I have two of these now, the original I got has trouble spinning up after you hit start, the parts TT has no output.
On the original I think all it needs is some cleaning/lubing on the large lever on top of the motor "base?" (large sheet metal it's attached to), but you can't really do much with these without removing those fine wires.
I've repaired headphones in the past with tiny wires like that, but I've also failed to repair them a time or two. Most of my experience with soldering is basic wire soldering where a "perfect" solder isn't necessarily required, and some circuit board soldering. I had a 10 week course in basic electronics about 15 years ago when I started towards my IT degree, but I've forgotten a lot, and haven't had a whole lot of practice since.
Part of my question is whether I should completely clean the solder joint, removing all the wires (including the RCA cables) and resolder everything, or just try to remove the tonearm wires and solder them back to the existing "pad" of solder.
Initially I planned to move the motor from the parts TT to the old one, but if the only problem with the parts TT is the RCA cables that the last owner unsuccessfully tried to repair, I might be able to get both of these working. The only other issues with the parts TT is the tonearm lift lever doesn't work, and the tonearm drops too fast.
