Need 17 position heater switch for Knight 600C tube tester - single deck, 17 positions (20 deg index) but 18 with continuous rotation would do. At least 3A contacts, I would expect. The wiper contact is mangled and I doubt I can make it work - I'll probably hardwire 6.3V for now.

As a suggestion, it may be easier to find a 16 position switch. You could then install a switch for Off for testing 0 volt tubes.

There are some on eBay that may work that they claim are 17 position:

Did some more looking on eBay - found a Mallory one that looks like the original. Not much space there!
