I was recently given a bunch of gear that had belonged to my dentist's father who passed away a year ago. A nice surprise to say the least.
Included was a TMC GPR 90 receiver that I would like to team up with the B & W 370. Both are in excellent shape for the most part except for two frozen controls on the 370.
My questions are these. Has anyone used the B & W 370 and is it worth fixing it's controls.
Any suggestions on freeing up the controls? I put a little penatrating oil on the shafts and let it soak overnight but they won't budge. There is no rust or corrosion on the unit at all so its a mystrey why they froze up in the first place other than age.
One is the volume control which I can replace but the other is the sideband selector/AM switch which special.
My feeling was to unmount the switch and remove the wafers and the retaining clip on the shaft and gently drive the shaft out and clean up whatever is causing the problem.

Steve,
Don't overlook where the switch shaft goes through the bushing. A little WD-40 is good to use. If you look at the wafers in the switch structure they generally do not freeze and if so are easily undone with a little lubricating cleaner. It does not take much but don't overlook a frozen shaft.
I have the B&W 370 that Jack Williamson gave me. Its a very good unit and well worth restoring.
Have fun with your new acquisitions!
