I like the set, by the way

I tried that, it wasn't happenin! I'll go back and try it again though. I had just uploaded the pics to flickr, perhaps some time has to elapse before they can be linked too, idk.

Here's what I do using Firefox. I right-click on the Flickr photo and choose the size.
Then, I right-click again and choose 'Copy Image Location'. I paste the result of that into the image tags [img] picture URL [/img]

You have a turntable? Im so jealous!!

Your set might be a Tarrytown.

We need to find you a set of knobs for your set now. Mine has all knobs, so I can take pics of mine for you as needed.

As I said, my cabinet is mahogany, so dark. The knobs are almost black/brown with gold inserts.

Matt,

That is a nice looking set. It should be a good challenge and appears to have been not abused. Enjoy and thanks for saving it!

That is a Tarrytown. I picked one up last year and have yet to restore it. Mine came with the original instruction manual. The guy I got it from had knocked the socket off of the CRT. I was able to put it back on and it tests fine but I don't know if it is going to work for very long. The original is a 17AP4 and I found a 17BP4 that tests great as a spare. The HV supply uses a doubler circuit with some black-beauty caps. The caps in my set are extremely leaky (~43k ohm) so the set will not produce HV.

It's a shame about the doors missing on your set but I think it still looks pretty good without them.

Yea, It is the Tarrytown model. Its a very good looking set and I've gotten good comments about it from non electronics minded friends I have shown it to. The pics don't show it very well but there are a few scuffs here and there on the cabinet and a few chips in the veneer. The left side has a big crack that will have to dealt with also. I have a coworker who's dad has a business refinishing antique furniture, so when I get the set working, I'll probably turn it over to him to fix up the cabinet and possibly build some reproduction doors. The turntable is pretty nice. It's a three speed changer. The tonearm is broken where it attaches to the base though. Yes at some point pretty soon I will certainly be looking for some knobs. If anyone has any leads on some, please let me know.

Today I took the chassis out and began cleaning it up. I also got out the dirt devil and de-cobwebbed the cabinet. It's going to clean up quite nice. I also tested all the tubes. Found 5 with weak emission, and one with bad grid leakage. I know this set has got to have a lot of hours on it. There isn't a single DuMont tube in there. Most of them are Tung-Sol, with GE and RCA coming in second and third. Interestingly the newest date code on any of the tubes was 1966.

My 113 doesent have any DuMont labeled tubes, either. I remember buying DuMont tubes in the 1970's, but this was long after DuMont went with Emerson.

I wonder if RCA was the OEM supplier for DuMont? My set is full of RCA's (silver label), with a couple of Tung Sol, Raytheon, and Sylvanias.

Judging by the labels on some replacement tubes, my set was possibly running in the 1970's, before the red-labeled RCA rectifier shorted out and killed the power transformer.
