Too bad this DuMont's not a tabletop
1949? I don't know DuMonts, and references are spotty.
With the small screen, I'm not sure it merits that much floor space. Guess it has a good sized speaker. Apart from that, is the audio section any better than most TVs of the time? Phil

If that's an RA-103, it has a real F/S discriminator, and one stage of limiting, a 6SJ7 1st audio, and a 6V6 output, at least that's what's in my doghouse. Average. But it could have a different amp seperate from the chassis.
BTW Phil, Thank You for posting the info on the RCA 8" personal portables. It was invaluable to me when I did mine! Kevin

Nice set but why is the tube off center?
It looks like it could be a 15". Are you thinking of getting it?

 Seriously, Has anybody here ever converted a floor model to a table model rather than pass up a desirable set due to space restrictions in the "TV room" ? I never have, but have thought about a couple of times. jr

Well, I'm thinking of going to look at it. Price is OK, but it's missing the knobs, the picture tube is loose (taken out for moving and not reattached), has a chip of veneer missing, and . . . it's big. I wouldn't cut it down, so I'd have to want it enough to have it in that cabinet. It's not like you can just run down to Target and get all those knobs.
On the plus side, it's a DuMont. I wouldn't mind getting out of my RCA rut. Phil

Looks like an RA-105 with a 15AP4, or 15DP4 CRT. I sure do miss mine, having to give it away when my parents sold their house last year.
Hope you get it, Phil! See ya, Matt Davala

It's a 12" set. Relative to the chassis, the 15" tubes are always positioned somewhat high and further to the left.

So, same chassis as a Doghouse? Control layout looks the same except that this eye's directly above the tuner.

I was feeling smug about escaping my RCA rut today until I spied Dave's $50 621TS and broke into tears for some unknown reason. Still, for $40 and a 5-minute drive, I shouldn't gripe.
Also included: RA-103 service sheets and a box with about two dozen tubes. The cabinet has a loose, warped top, and some other boo-boos, but nothing I haven't dealt with before. Check out the ginormous box cap strapped to the top of the HV cage. The "repairman" wired it in parallel with one of the p-s filters.  Something mysterious happened inside one of the 5U4G rectifers, but there are two more in the spares box.Won't be trying this out any time soon. It's #4 in the project queue. Anyone know the name of this cabinet? Oh, I need a complete set of knobs, too. Later . . . Phil

Nice, I think you'll find that chassis is very easy to work on, lots of room.
Wonder what that big capacitor on top of the high voltage cage is for?
