VZ2000 Playing too Fast Side A, Too slow Side B

[Uki]

I have basically finished my restoration of my VZ2000 - Ive used 2 to make 1.

Seems the LPs are playing a tad too fast on Side A, and A tad too slow on Side B, Particulary near the end of the side.

My parts box is a VZ2000X and my Finished job is a VZ2000Z - Is there any difference between the makes? I know the X Model part box has MW/SW/ Radio and Din Imports for Auxilary, but thats the only difference I can see between the 2.

The reason I ask is I am using the Record Player mechanics of my Parts box (VZ2000X) with the main board from the VZ2000Z and was wondering if this could be causing the issue? Or is there a way to alter the speed?

Did you check 45's?

There is a variable resistor for motor but doubt that's it since you have opposite on each side. There is a scheme and if my memory serves me there are 4 transistors that are part of the control for motor and 1or more may be bad.

i coulda swore there was a speed control screw on the main turntable pcb . sounds like the belt to me , unless you put a new one on it these belts get flat spots in them from sitting in one position too long .

45s are going too fast. ive not tried side b.

Not sure about a speed control would look like. I'll have a closer look. are the resistors near the motor? Not sure that would be it but I'll have a look and get back

Here is scheme

Hmm. Thanks for that. Well something strange happened, I have 2 belts (both new) - and I replaced the belt with a different one from the parts box (from studio sound electronics, Original one was from Ebay) - The new one seemed a little looser.. now it is playing way too slow...

Not sure if this eliminates or highlights the belt as an issue?

Beforehand with the original belt, side A was playing too fast, as was half of side B. The later half of side B was playing too slow particulary towards the end of the LP.

Here are some shots of the motor/PCB. None of the capacitors seem flared or anything and all the lights on the switch are working fine..

I do have another motor I could try which could help? But then it might be a fault with the board/microcomputer?

If your speed is consistent and belt seems tight enough then you can try adjusting these variable resistors. One is for 45 speed other is for 33 speed. Good luck.

With seeing the dirt you have I would also try cleaning these variable resistors with a switch and contact spray then turning them back n forth. These also do not fully turn all the way around so be cautious.

Ahhh I see. Thats awesome. Thanks. I have put on the original belt and calibrated it to the spare box settings. Cleaned it all up and ended up fixing a few other bits with JB weld while I've got her open and drying.

These things all take patience.

I'll report back. Hopefully good news soon!

Thanks again.

Update - Thanks so much, its all sorted now, playing right - adjusted the capacitors as per the old board and every function is finally going on it!

Patience is a big one with this box, but the reward is worth it!

Just need some sliders now which should not be too hard and all will be good !

That is awesome!!! For new sliders PM THAFUZZ. as he has a guy who makes printed ones and they are even better than original
