Does anybody have a link to a scan of an old data sheet for the 811 (NOT
811A) tube? All I seem to find are 811A spec's. I have the two line
blub on the older 811 in an old ARRL HB, but I'd like to get the
complete spec sheet. This tube existed in the gap between the TT3 and
TT4 tube manuals so I can't find it.

Here we go:

Thanks, but that's NOT it.
This link goes to the Svetlana sv811-10 which is NOT the same as the
ORIGINAL RCA 811 transmitting tube. Svetlana had no right to call this
bottle an 811 as it does NOT have the plate cap, is NOT a transmitting
tube, and has a mu of 10 not 160!
This is a nice AUDIO tube, more of a replacement for the 300B than an 811!
