Hello,
The counter weight droop concerns me too.
Anyhow, Happy New Year!

The "counter weight droop" is a non-issue.

If you can dig up the owner's manual or vintage advertising photos from the internet, you'll see the "droop" on brand new machines.
 
The rubber in the counterweight does not age well. I have one that actually hardened, and crumbled. Looked like Oreo cookie crumbs.

If it's not severe, don't worry. If it's dragging on the deck, you can clean it out and use silicone to rebuild it.

The turntable was stored for 15 years in the Michigan temperature extremes. I also broke the anti skate trying to fix the counterweight.

Surprisingly, the feet can still hold an L75 with two stacked heavy platters. :dunno:

BTW, I don't know if anyone else knows or even cares, but it is possible to play a 16" transcription disc on the QL-A7. The clearance is a no more than a few millimeters, just enough to get the job done.

Really? I had no idea. This is very good news to me. Thanks for the info.
 
I didn't realize that thread I linked to was so recent. Have to keep an eye on it. It appears also from reading it through in more detail that the washer may not be a complete fix (related to original bushing extending into each side of the arm and the counterweight shaft).

My table is still working fine - no channels dropped out today.

So far the droop is not an issue on mine and the rubber seems to be in good condition. As I pointed out previously I'm pretty sure you can see the 'factory droop' in the service manual or user manual for the QL-A7 (go to vinylengine.com).

They came from the factory straight, no droop. Mine took about ten years to develope a sag.

Maybe the apparent 'droop' in the pictures is a result of the horizontal 'kink' between the arm at the pivot and the counterweight shaft .... optical illusion.

My left channel's still there.
