Restoring a B&K 1570 analog scope (actually a kenwood cs2070 in a B&K box) that was badly damaged in shipping. The seller shipped it in a used LL Bean box with about 4" open space all around with no packing material
Needless to say, it was rolled into a ball, but I got a full refund and got to keep the scope. Amazingly, the CRT wasn't damaged, and I've finally set about making repairs. I've been able to repair it electrically, but I'm hung up at this point:
The outer shaft on the a/b intensity control, a concentric 1k pot, has sheared off right at the standoff. I could mount another pot somewhere else, but it's the B sweep intensity, which I honestly won't use much if ever anyway. So, in the interest of honorable restoration, I'm trying to save the functionality of the original component.
So far, I've cut off about 1/8 inch of the standoff to expose more of the brass shaft. Then, I drilled out a little of the brass end so it fits snuggly on the exposed shaft. Looking at the pictures, would you attempt to braze this? I'm afraid solder won't hold. (Disregard the center shaft in the picture, I would obviously have that out before attempting a weld).
There is more of a gap between the brass end and the standoff than visible in this photo, allowing access to the joint.
