We're working on a DuMont RA-110 that's in our New Jersey Antique Radio Club museum and one problem is that the focus control is open. This is a 1,000 ohm 25 watt pot, and to my experience this is not a commonly available item.
A couple of questions:
These seem to be open in most of the DuMont sets I've worked on. Could this be an indication of a design flaw or be considered a "high failure" item?
Does anyone have a spare one?
Or any experience successfully substituting fixed power resistors with or without a pot of a different value?
Thanks!
