Very neat acquisition, Tom!

I do think, however, that someone just stuck some tubes in the front end of your radio - it should not have a UX-199 and a 71A, but two 01A tubes. The 199 requires a lower filament voltage than the 01A.

I've heard of the Daven tubes. Somewhat rare, I believe. If your set has an entire Daven three tube amp, that alone may well be a real "find." In that case, the radio should probably use a 201A RF amp, 201A or 200A detector, then the three stage audio amp.
