The Mike New Technics Bearing

[MikeMusic]

Yes Michael, I had that same mod and had to remove it when I bought Mike New's heavy platter. The warble on 45 was very noticeable.

Wonderful
I think I can count on the fingers of one finger how many times I have heard the reason for some problem like that.
Deeply satisfying

Hi Karl,
In a conversation with DC some time ago he said that the mod was to allow the "sound" of the SL to resemble that of the LP12. Although, why anyone would want to do that is strange. Excepting that maybe the modified Phase Lock Loop characteristics resembled the affects of a rubber band driven TT. on the heavier passages of music.

With the CR values that were chosen, the Mod should be removed on any SL using a heavier platter than the OEM version. As Martin and others quickly discovered.

However I would not think that it would cause any problems when using my Bearing.
Maybe Nick does have a pitch control problem which is excerbated by fitting my bearing.

Nick, check to see if the pins on the plug from the slider are clean and do not have any oil or dirt on them. This should not be the case but it is worth checking, clean the pins with Acetone.

I have tried running my test SL without the slider plug connected. The speed was slightly higher and less constant.

Mike - could I just be clear here - ''I have tried running my test SL without the slider plug connected''. This is without the plug OR a shorting block between required pins I take it as in the pitch fader removal mod?

Hi Stephen,
All I did was to remove the plug (4 wires) to simulate an open circuit caused by dirty contacts. This obviously is not what anyone would want to try in practice. There was some semblance of control but far to fast.

Hi Martin. Would there be a chance of any pics showing how to disable this mod?

Hi John

I don't have a photo of when it was installed, but you can see a cap/resistor in parallel soldered across an existing component (sticking in the air) on the PCB at bottom-right as you face the deck. I don't have a layout to hand (I'm at work) but shout if you want the location and I should have the diagram at home.

Hi folks,

I don't think Nick's problem is related to his pitch fader problem.
Of course, the contacts need to be clean (I use isopropyl alcohol to clean contacts, sometimes called isopropanol, available in any pharmacy, cost next to nothing).

But when the pitch fader is at zero and the led lights, the entire pitch fader cirtcuit is bypassed.
There's no need for a "pitch fader removal mod".
Unless you want to remove the fader from your deck, in that case it becomes an aestetic mod.

Woo Hoo,bearing has just arrived

Time to install and see what we have.

[kininigin]

Everything is installed and is up and running fine.

Very early first impressions DAAAAYYYYYUUUUUUUMMMMMMM!!!!!!!!!

See you later,i've got records to listen to

Look here at an old photo of the bottom-right hand corner of my main PCB. You can see a red capacitor and a resistor soldered across an existing component. That is Dave Cawley's Motor Dynamics Mod, which reduces torque. Cut those two components out and you will revert the board to standard operation.

Thanks. Mine is untouched by DC. I wasn't sure if mine had been modded.
