I just realized I have one of those sets too.

hmm I do not have any of them particular instruments.
I guess these sets are quite common I've seen some other collectors with them too.

You have to remove the cover check for play. IIRC, the rear one.
The proceedure for repair is to properly center the disc and carefully drill a hole through the hub and the shaft and use a cotter pin.

Make sense. Too bad I didn't notice that when I had the tuner pulled apart for cleaning.


Well, I got measurements from the 3 tubes that have the most to do with the sound. I've got some that are way off...
