Thanks for your reply. I have started a conversation with you regarding the tachydisc.

BTW, the aluminium piece that surrounds the platter is loose. Would it be OK to glue it with epoxy, or must it be glued with doublesided adhesive tape as it was originally? 

I have chose to glue the aluminium panel above the tonearm with epoxy, as it kept falling off.

Epoxy will be fine.
Rememer to account for the tiny spring that sits in a hole near the leftmost forward corner.
It connects to the underside of the aluminium surround for static discharge.

Hi all

This is an quiet old discussion but I stumbled today over this.

I had a similar problem with a humming at each relevation of the platter, even with a new lasercutted tachodisc from Dillen.

Today I decided to put a small amount of T 7000 glue underneath the black subplatter ( only at the inner hole and only a small amount) just to fix the subplatter to the spindle.

The glue is usually used for mobilephones to attach the backcover, and you can remove the glue easily with your fingers, peeling it just of.

The humming was gone in seconds.🤩

There must be a tiny gap between the black subplatter and the spindle with the tachodisc. A little rattling which is audible through the pickup system.

In my opinion there is a constant regulation for the speed and this regulation is always working a little (very little) bit because it´s a dynamic process to keep the platter at a constant speed.

For me it was a solution and I´m happy again to listen to my records without a humming between the tracks ;-))

Stay tuned.

Best regards

Hi Christian,  I think I have a similar issue, but not so much humming, but more of a wiper blade sound

Hi Peter

If you start the player as usual and drop the tonearm in the endgroove of the LP there would no music disturb the "humming".

So for me it sounds like the humming from the motor just like I had.

But before more investigations are made, please check the tachodisk for any damages.

Maybe a platterweight would help a little bit, some centerholes of the vinyl are drilled a little too big and when the vinyl is leightweigt and maybe bended a little bit, the humming comes more to hear.

Kind regards

Christian
