VT-1 tube data can be found in "Principles of Radio Communications"https://archive.org/stream/principlesofradi00moreuoft#page/554/mode/2up
on page 573. Don't know what you mean by accurate since tubes of that era were a crap-shoot.
I have a few VT-1's to lend, if this will help in your testing. Some used, some NOS.Jim, Hot Springs, AR

I am thiiiiis close to firing-up the BC-9. Got to
find a better sub for the RF Osc/Det. The 01A
works fine in the audio amplifier but lacks the gain
to oscillate in the RF stage. With a change in bias
battery, a triode-connected 6AQ5 will oscillate but
I would like to find a better match.
Does an accurate datasheet for the Western Electric
VT-1 tube still exist? Google is no help at all.
There is a ton of incorrect stuff out there that gets
repeated and repeated, mostly equating this
01A-like tube with the 203 transmitting triode
or listing a few specs that are completely bogus,
like the wrong filament voltage etc.
Anybody?
Thanks. 73 DE Dave AB5S
