That poor chassis. I sure hope it is fixable!

Not to worry. I think it will be saved. Chassis looks a little rusty, but probably can be cleaned up to look and work real nice.

Yup...I'm going for it.

Hope you get it....Will keep my fingers crossed.

I want to collect all of the early DuMont RA #s. Also, I've always wanted wanted one of the DuMont "Bar" or "Club" Telesets. I've restored a couple of DuMonts, and the RA-105B "Sussex" I did is a close cousin of the RA-106, so I shouldn't have any problems. Hope the CRT isn't dead.

...all I need now is a Bar to go with it.

Hey Lee , count me in for the ride to pick it up.

The RF frequencies for channels 2-13 were standardized by then.

I was wondering whether the set will work with a box because of the IF strip, not because of the tuner. If this is a late 1940s set, the video IF may be 28 MHz (which, BTW, is why so many of these early sets would pick up local amateur radio operators transmitting on ten meters) or some other oddball frequency, not 41 MHz as all sets are today. Aren't the converter boxes set by default to operate only with TVs having 41-MHz video IF strips? I don't see how a modern converter would work at all with any TV made before 1960.

Wouldn't the difference in IF frequency have a bearing on whether or not a converter box will work with a given set?

NO! It will not make any difference at all. A DTV converter will work with any set that can be tuned Ch 3 or Ch4. The exception to this would be pre-wwII sets that have 441 horiz scan lines rather than 525.A scan converter box would also have to be used, as well, to make it work.
I have used DTV boxes on several sets with the old 21 mHz if... they work just fine!

Actually, no scan converter would be required for a prewar set. The horizontal controls will adjust to the 441 line signal just fine.

I am not sure how to interpret that statement...are you indicating that:

1.The DTV converter box has some internal adjustments that allow it to be set to a 441 line horizontal frequency.

or:

2. The old 441 line sets have enough horizontal frequency range to allow them to be easily set to 525 line rate.

or perhaps something else?

[Steve McVoy]

2 is correct. They have lots of range.

Cool!

I can see this set running in its original setting... People watching the fights, or some other sports events, or maybe watching Gleason's variety shows. How Sweet It Is!!

Keeping my fingers crossed here, too. My DuMont RA113 is rallying for you, too.

Hey Lee,

Would you still drive up for it, if you don't win the auction.......
