You may have to work from a set of similar schematics. I wonder if the schematics for the Crosley 51 and Trydyne in the schematics section of this site would help. They cover 2 and 3 tube radios that would use 199's or 01A's. I think radios of that era were all very similar.

A radio using three triodes isn't that complicated, I should be able to figure this out without too much
trouble. The schematics you suggested are similar. In this case a schematic probably wouldn't really help
much because component values aren't listed on most of the old schematics anyway.
I remember in 1969 I was working with an old radio repairman that told me one day that Howard Sams had
ruined a lot of good technicians. When I asked what he meant by that he said everyone was so used to having
a schematic with all the voltages and values that they couldn't figure anything out for themselves any more.
Thanks again, I guess I will figure this one out for myself.

: Hi, I have looked in the Radio College of Canada schematic books and find that your radio is too early to have been included in them.

UX199 is the same tube. The later designation for this tube would be X99. If you reduce filament to 2 volts you could substitute #30 tubes.
Resolder the two large pins on your open tube. Sometimes it's only a wire to pin contact problem.

: I have a Canadian Westinghouse 53 Regenerative receiver with a patent date 1922. It uses three WX199 tubes.
: Is it correct to assume that this is the same as a UX199? (one filiment is open) I have not repaired very many

I usually don't work on radios quite this old but this one originally belonged to my father-in-law and I decided it would be fun to make it work again.
I didn't get lucky with my tube, resoldering the pins didn't fix it. I will have to find a replacement.
