Hi There!
It's my first post, but I'm reading a forum for a few weeks already.
The amount of the information you all share is AMAZING! Thank You all for that!

Back to the project:
L85 second generation electronic.



At first blik it looks nice. But with close lookup there are few things to fix.
When I get it, it turn and make a sound (one channel, and other was noisy)

Issues I found
 Mechanical:
A. Cover have some cracks in two places and some burning mark.
B. Plinth to replace or restore (someone do the crapy paint job)
C. Tonearm is a little rusty, but its moving smoothly
D. Antyskating is missing
E. Lift is stuckt and cracked
F. Pulley is dirty as hell (done - it's clean)
G. Belt is from something else (is to loose and to narrow)
H. Base plate is not centric on the plinth.
I. Springs are soggy and do not keep everything at one level.
J. Turntable platter was cracked and glued by someone blind.

Electrical:
1. Speed was on another planet, to slow and not consistent (done - change all capacitors, and do the calibration)
2. Some wires are not connected on both sides at tonearm.
3. Auto stop is not working.
4. Transformer is noisy.

I found a lot of answers already on forum, but have a few one already and more for sure to come wink

First question:
I have a cable thats not connected at the tonearm conectors (sorry if I name it wrong)
Should it goes to the connector, pointed by white arrow?

Replacing the capacitors is only part of the job. You should replace the carboncomposite resistors as well. They drift about 10-20% in value over time.
Fellow member Max (forumhandler Macuser) has written many great and helpfull posts about the electronics of the L85.

Yes, it should be connected to the point with arrow nr 2.
This is a spot where more ground/earthing wires come together.
The loose cable is connected to the GND of the right channel audio cable.
Maybe someone has cut it to solve a hum problem because of a ground loop.
If your music sounds correct with no hum: leave it be.....

Have fun restoring this nice L85 !
