@andlum Off the top of my head compete service should include:
-The suspension has been checked and adjusted. Every tech will do this, I'm sure it was.
-Motor inspected. Ask if it has the original motor. It's fine if it does.
-Change bearing oil. Ask about this, very important. If not, how long has it been since it was done?
-Check condition of the belt. Ask if it's the original, mine lasted a long time.
-Make sure 33 & 45 speed control works.
-He did the caps and I'm sure checked voltage and it's up to spec.
I think that's it. If there's no manual, you can find instructions on how to balance the arm online. Oh yeah, many older Linns have broken hinges on the dust cover. Usually they can be found on Ebay.
Best of luck, I'd really like to know if the table works out for you.
