Hi;
I'll be glad to show you some additional interior chassis photos. I'll post them within the next day.

Thanks.
Bob

Attached are some of the DuMont chassis pictures. The set is exactly as found, so there's some dust and dirt, but not much. I don't see any chassis number on the chassis, and the ID tag on the rear removable panel is missing, so I don't know what model chassis this is.....

I've also included a picture of the convergence board, the tag on the CRT, and the solid state amp section which looks pretty substantial compared to a lot of the amp units found in these combos.

What does it look like?

Bob.

What is the stamping on the third photo below the controls on the left?

Looks like 735-U.......

The convergence board parts numbers and positions sure match up to same from a RCA CTC-16.....

[marty59]

Wow! That is a pretty clean chassis..a variant of the RCA CTC-15. Howard Sams number for this will be earlier than Photofact Set 823/dated July '66. This is the H.S. for the later 25" version. If you have a library that stocks them and an index book I would work backwards from here.
I'll take a look at my index book and give you some better ideas too.

[marty59]

Here's a clue....Chassis number (if you can find one) will be a six digit number beginning with 120xxxx. Possible numbers 120699/1207xx and this would point to the direction of Howard Sams 724-3/3A. The "A" would be like a remote chassis. The radio chassis will be under another Howard Sams I would believe but 724 may be of some reference to that.

Other H.S. numbers may be 650-1, 598-2, 576-2....but these are getting quite a bit earlier but the chassis number would still be starting with 120xxx.

Even as a point of reference, an RCA CTC-15 is H.S. 673-2 so it shouldn't be earlier than that.

I checked the chassis and found no useable numbers to ID it. Other than some part numbers...I see nothing that resembles the potential chassis number you mentioned starting with 120XXX. The code date on the factory original tubes is 1965.

I've included a scan of the tube layout...I don't know if that's specific enough to be of any help, but I thought I'd include it just in case.

Thanks.
Bob.

The tube chart kind of clinches it as an RCA CTC-15 or clone of same.

Thanks for that information Steve. I still need to determine a DuMont/Emerson model or chassis number to get the correct Sams for it. I'm guessing this combo known as the DUMONT LA TRAVIATA was a 1965 model and would therefore be in one of the Sams released that year. I don't have access to all of their Photofacts and the ones I do have are much earlier.

Just wondering if anyone might have the Sams for that year and could browse through them to see if this DuMont might be included? Or if you have the Sam's index to check for the DuMont models released in 1965.

Thanks.
Bob.

Bob,

I checked my SAMS index, they list by chassis number (120XXX various numbers) I agree with poster marty59. Your set is in SAMS Photofact set 724, folder 3. Your photo shows a 735U stamped on the chassis back. SAMS shows a 120735A/735B among others in set 724. This may just indicate a different finish or model. Hopefully a fellow AK'er can provide the folder or you can Google SAMS Photofact and order one.

Thanks Steve (and marty59);

I'll order Sams 724. I appreciate everyone's input and help.

Bob.

A very good chance I have that Sams available, if you haven't ordered it yet. Aside from the massive (but incomplete) set I have, a local TV repairman is bringing me several hundred a week from his stash. His are extremely complete from the low hundreds to wherever they were 5 years ago or so.

The 69/70 model DuMont I have uses the horizontal/vertical chassis, which seems to show up starting about '67 in rectangular sets. I know that the back of the convergence board has the name "Emerson" etched into it. Don't forget to look for EIA codes, though with a company like them I doubt they made much in house.

[JohnAdams]

Just curious as to who built the CRT? Does it still have the E.I.A. code on it?
I think I have the original brochure for the DuMont 21" sets but will have to did out of storage. Funny thing is I don't recall the "Emerson" being mentioned. Would early DuMonts not include the Emerson name??

Your cabinet looks like one I saw in the brochure. I was always partial toward Italian styling.
