The cad plated chassis is well preserved under all that dust.

All caps and resistors appear ex-factory.
Ever give a second thought about keeping it in its completely original condition? Relatively speaking "restored" "working" 621ts' are a dime a dozen, but examples as original as the one you currently have are probably quite rare, and getting rarer every day.

RCA changed to a year-week code in 1946 so 6-17 is 17th week of 1946, if there is a dash it's an OEM tube, no dash it's a replacement tube.

Before that the code was a letter (Year) number (Month pair) combination, U=1937, F=1946; 1=Jan/Feb, 6=Nov/Dec, so 3-43 isn't an RCA date code.

In 1956 they changed again to the RMA-EIA code format YY-WW.

The latest tubes are 6SN7s, all dated 6-30, with a dash. All the tubes have dashes.

I haven't ventured inside the HV cage yet.

Soooo...6-30 is Mid-August. The sound discriminator is a 6AT6. An early production 621TS. Say, September 1946?

Looks low hour. And the latest tube date code is 6-30

Where is the date code on the CRT?

She's up and running. Has audio has a raster but looks like the horizontal frequency is off. I can't find the hor.frequency control like in my 630TS.

Anybody know...?

Should be on the base somewhere. I'd have to look at mine. This is a nice one. Bet you paid 4 figures. If not - what a deal.

You're doing the Right Thing... A set THAT good deserves a chance to "Live" again.... It will likely "Wow !" as many, if not MORE people now & in the future as it did in 1946...

Very nice acquisition, Lee. Since this is a walnut version, are the center trim pieces and left and right stripes lighter in color than the knobs? That seems to be the one way I can tell a walnut set from a mahogany one.

They are about the same tone.

OK, so I cannot use that as a way to tell either. Well, maybe mine IS walnut, then. Every time I try to compare it to other sets I have or look at it in different light or a different angle, I see something that makes me not sure one way or the other. Thanks.

Great find. Even 70 year old dust!

Can't wait to see photos of it up and running.

Oops. My error. The sound discriminator is a 6AT6. Original tube.
