I did a bunch of writeups on early DuMont sets for Radiomuseum.org. Here's the story on the RA-113 and its relatives: http://www.radiomuseum.org/r/dumont_...ra_113_b7.html

You can find information for RA-101, 102, 103, 104, 105, 108, 109, 110, 111, 112, 113, and 119 there if you explore a little. Pictures and schematics for quite a few of the sets. Schematics also at the ETF site.

If you see any errors in the information, let me know.

THANK YOU!
This clears up the the confusion about the various different RA113 models. It also appears that some of the info on the TV history site is in error... the 19" roundie is not a 113 but likely a 112 and the Tarrytown-looking set shown is indeed 17" like mine, not 19" as indicated.

Ps: my RA-113-B7 has a glass CRT...should be a 17AP4, but IIRC, a more common 17BP4 was substituted.
