Luxman PD121A - PD441

@lewm  its a 50/60 model but i have a step down. 

I have followed some steps that the seller has suggested and its just not working right. The table turns even when I havent clicked the ON button. Power is on and it just runs! I thought it was going to fly off and hit my wife in the head hahaha

So sad :( Back to the drawing board i guess. Suggestions on which thorens or a sondek?

“50/60” is a reference to AC frequency not voltage. Somewhere on the chassis near the AC outlet or the fixed AC cord outlet there will be a recommended voltage noted. Probably that’s not your problem but worth checking.

 its a 50/60 model but i have a step down. 

Japan domestic market has both 50 & 60 hz power grids.

If it says 50/60 it should run on both frequencies.

If it is Japan domestic market it is 100v and you need the step down transformer.

The table turns even when I havent clicked the ON button. 

This suggests there is a circuit fault affecting on the start/stop selectors.

A competent technician should be able to fix this - the circuitry is pretty basic.

Luxman 441 speed adjustment - 

If you have intermittent speed lock issues,

1 . Remove the name plate from the motor cover located on the under-
s i d e o f t h e u n i t .
2. Remove the motor cover (be careful n o t t o damage the rubber
bushing).
3 . Adjust the D.C. voltage on both sides o f R12 on the circular Printed Circuit Board to equal:
Speed Adjustment

First adjust VR01 33 1/3 rpm too get 7.5V
Then adjust VR02 45 rpm to get 8.5V

N o t e :

Variable Resistor (VR) must be turned very s l o w l y.

33 1/3 rpm should be set first and then 4 5 p m .

Platter MUST be in place when making the adjustments.

Also do not adjust the speed until you are running at the correct voltage.

In a nutshell a good tech should be able to solve these issues - the circuit diagram for the controller is freely available on the net.

Dover is essentially saying don't give up, and I agree with him. You have a very nice TT there.

Funnily, if it is a 120V unit and you are using a 120V to 100V stepdown, that may negatively affect performance. Line frequency 50 vs 60Hz does not matter because the built in power supply is going to convert incoming AC, whether 50 or 60, to DC to run the motor.

its a 100 model and i had a step down / up conveter. I have purchased a few laserdisc players from japan so have them lying around the house haha

But the thing is really wacked out and I dont have the time or the will to have someone play with my money when i could use it elsewhere.

Shame though as its a beautiful machine
