Stop in for a cup of coffee

I replaced the square drive belt in a cassette deck with an o-ring. Worked perfect.
This things need just a few tweaks. Speed adjustment, check head alignment, and the Sansui is having some control issues where the bottons don't do what they are supposed to. That may need parts. And thats why it cant be the guy with some belts and a can of deoxit. Been to a couple or three of those.
If I got a scope I could do the speed and alignment using a master but really dont want to. I want to pay someone who already has the stuff and knows what he (she?) is doing. Also knows what parts can be had and from where.
