Hello!
I’m working on repairing a Luxman turntable and having a bit of trouble with the power rails.
The 5v measures at 5v
+15 measures at 14.75v
-15 measures at -6v
I’ve attached a schematic of the PSU board and I’m hoping for some suggestions. I’ve checked all of the capacitors - and replaced a faulty Zener diode (DZ02).
Hello!
I am currently working on repairing a vintage (Luxman PD-441) turntable. I (think) I've narrowed the problem down to faulty Hall Effect Sensors. When I opened it up it looks like they've been worked on before - due to the soldering.
Regardless - what do you make of this? And would anyone have suggestions on the type of hall sensor to use? Unfortunately there is no schematic for this motor. I checked continuity around various places and it's good at the connection points but I don't know if there's a better way to test the sensors.
