Mark Levinson 23

This oldie had all low value electrolytics faulty. One channel has very low distorted output. +12v missing. Anyone with circuit diagram?

Or do a search on the forum, the schematics have been posted here.

Thanks but can only find operation users manual and ML2 circuit.
Where is ML23 circuit?
It looks as if I am in for a long desoldering job to get to reverse side of pcb!

Mmm,
if you're any good, you'll know the difference between a 23 and a 23.5

Here's what i get if i type in ML23 and Peter Daniel after i hit the search button.
Want it gift wrapped : ask Santa.

Don't electrolytics when old and leaking their fluids make a mess!
Print on reverse of pcb open circuit due to the corrosive effect of the electrolyte after all this time.
Anyway ( thanks to your help and the circuit diagram) the amp is now in perfect health.
Merry Christmas
