Available in nine different colors: black, white, dark red, pink, light blue, light green, grey, dark brown, dark green.
Model versions (chassis) were 811-A, 811-B, 811-C, 811-D, 811-E (Series A, B, C, D, E) reflecting presumably minor circuit and component changes. Which colors were used for which series is only partially known. A member has tested the case of a black 811-B (with chassis 120228-B) and wrote: This cabinet looks like a plastic mould but is really Bakelite (fibrous material when broken and a formaldhyde smell when warmed). You can see a swirl effect in the molded body. Somebody else insists that it is modern plastic - and his model does not show a suffix (like B). Therefore we chose to leave the question open until finally cleared with good facts. Mabe there are both versions - but depending on what?

Beitman 1955 (Vol. 15-25) shows one same schematic for 811B Ch=120228B, 812B Ch=120229B, 813B Ch= 120230B and 822B Ch= 120232B and adds: "The circuit printed on this page is exact for 812B (has 2 speakers). 813B is electrically identical except that it uses but a single speaker. 811B also uses one speaker and T-1 grid return terminal #3 goes directly to B Neutral. 822B is like 811B with the addition of a "Jack" for attachments. Beitman shows "12AV6 or 12AT6" for the 2nd Det-AVC-AF Amp.

Photofact 4-55, set 274, folder 8 shows the same schematic for 811B and 822B. Range 540 - 1620 kc. Same alternate tube is listed. Only the Mascomite Back ist different between 811B and 822B (probably only the designation printed) and a slightly different AF output transformer. See also resistors R8 and R9 for the Earphone Jack on 822B only on the secondary of the AF output transformer. There seems to be no separate SAMS for 811A, 811C or 811E but in the index is included 811D for this set 274, folder 8. For 812B / 813B is given 272-6. Optically, 811 (looks like 822), 812 and 813 show quite a different case.
