There's a guy on ebay that does a similar refurb for $680 plus shipping both ways. He checks the resistors and transistors but doesn't do the tuner recap for that price.Just a ballpark figure what would the irk you've don cost if you had to farm it out.......if you could find a shop that can do it?
I know one thing, I would never pay that price just for a recap.
FrenchKris- what do you mean by "FMstereo imaging disappearing from time to time?"
What a machine!...

What size allen wrench did you use to remove the set screws from the tuning knob?
