Hey guys, I just successfully repaired my Philco 38-3 AC/Tone control 3 position switch with the help of Mark Oppats advice. I just used a feeler gauge, a dremel tool, some sharp drill bits and a package of BBs that would go into a BB gun since I lost my original ball bearing. I used the .33mm size feeler gauge but next time I would try a bit thicker. I’ll post some pictures and a link to the video. If anyone needs help with a similar repair let me know. Anyways it worked out nicely. Here is a video of it in action after the repair:

GREAT JOB John !
If that spring steel part is not strong enough, the ball bearing will want to "jump" out of the hole you drilled for it to ride in when actuated quickly. So as long as a kid doesnt twist that knob fast, you will be ok.

The Zenith 85-109 "Off-On-Local Distant" switches are just like this too. The same type of part fails, but its a bit different shape. You could do well to off this service here on ARF or make up a listing for Ebay and do it., lots of these have failed for the same reason and can be fixed.

If you scratch that end cap more with an X-acto knife, it will take solder better and hold stronger. No need for the wire.
