While waiting for the new 1B3’s, Mike fixed a broken knob. The tone control is little used, so should not be a problem.
UPDATE, SEPTEMBER 2, 2019, DAY 394
From Mike: “Hi Marshall. I am working on other small things while I am waiting for the new HV rectifier tubes. So, here are the images of my repair for the tone control knob. I believe that you have the volume/on/off and channel select knobs and they have been re-plated. Question: Are these knobs that I have here which are white in color supposed to be gold in color? This tone control knob looks like it was gold at one time. If so, I can shoot them with some paint to make them match. Let me know if you learn anything about that.
Photo #1 First step. Re-attaching the broken piece to the main part using JB Weld epoxy
Photo #2 The first “real” layer of epoxy over the repair.
Photo #3 I used electronic lacing tape (very strong stuff) , tightly tied around the previously broken part for added strength. Then added a second layer of epoxy.
Photo #4 Finished and ready to re-install the circular spring. Not real pretty, but likely won’t break again. And nobody sees this part.
The other white knob is for fine tuning and they will both be cleaned with a solution of dish soap and water using a small brush. There are two other knobs which are plastic and gold in color and may need polishing. I will be careful if I attempt to do so.
West 32 coming soon. Mike.”
