After a few more tweaks, I declared victory on the electronic front and put the RA-102 into its cabinet. I posted an article about the restoration here:

http://antiqueradio.org/DuMontRA-102...Television.htm

I'll refinish the cabinet when the weather improves.

Thanks to everyone for the generous advice, in this thread and others. Now I can launch the next project -- an Emerson 609 projection TV!

Regards,

Outstanding job I'd been wondering where that 3rd Buk Clifton ended up. Couldn't be in better hands

Great job!

It looks like the cabinet could use some touch up yet.

Yes, I haven't touched the cabinet yet, apart from brushing off the dust.

That reminds me, I'll need a Dumont logo decal. It looks like ETF no longer sells them. A guy on ARF has some spare RA-103 decals, but the logo in that set has jagged edges.

The RA-102 and RA-103 logos aren't identical, anyway. The RA-102 logo is 1/8 inch wider than the RA-103 and the letters are thicker. The RA-113 logo is wider still.

The RA-102 control decals are on the knobs, not the cabinet, so none of the RA-103 control decals would work, either. The RA-103 letters are too big and the curvature is wrong.

My Clifton still has it's original finish and "Dumont" decal. I can take some photos and measurements.

The finish and decals on my knobs was quite deteriorated. I've stripped them in preparation for refinishing but not sure what to do about the tiny decals.

Here's a closeup photo of the logo I took back when I got mine. You can faintly make out some letters on the right knob.

Are the controls knobs in any better condition on yours ?

The Dumont logo on my RA-102 looks like the RA-113 logo, only slightly smaller. Here's the RA-102:



The RA-113 is about 5/16" wider:



Perhaps a decal maker could reduce the RA-113 image to make one the right size for the RA-102.

I originally thought the knob legends were tiny decals, but now I see that the letters are recessed. I think they stamped the legends into the knobs and then filled them with gold paint. The legends on this knob say TONE and ON-OFF:



If your knobs are stripped and the stampings aren't completely worn off, perhaps you could brush gold paint into the recesses and then wipe off the excess. That might work on some of my knobs, but on a couple of them, the letter recesses look worn away. A person with a steady hand and a tiny brush could touch those up freehand, but I suspect my fine motor skills aren't up to that task.

I notice your set has six knobs wile mine has five. I believe mine is the earlier version which could account for the logos being a bit different - mine has an outline.

Most of the recessed letter has worn off my knobs. I think for the time being I'll just leave them be.

Yes, the earlier version (RA-102-B1) doesn't have the focus control in front. The later version (RA-102-B2) has an additional 30-ohm/10W resistor on that control. Riders lists three other small changes on page 1-43.
