So, If anyone should have the same problem in the future and stumble upon this thread, the problem was capacitor C4.
The datasheet marks it as a 0.1uf capacitor, but in my PL-400 it's a 0.15uf capacitor (of the mylar/polyester type)
I've replaced this with a new polyester capacitor and the...
I've got a Pioneer PL-400 that seems to be having some speed wobble issues. I got this turntable several years ago and it was not working at all.
One of the large caps for the motor driver had failed (C10, C11, C12, one of those) as well as the trimpot for 33rpm had broken (VR1). The trimpot...
Hi, I recently bought a PL-400 cheaply with the speed running slow. I fixed the speed by replacing the trimpots on the motor control circuit board. It seems to be working fine now.
I had some questions about the behavior though. When the turntable stops, is the platter supposed to freespin...
