Hello,
The TT22 is another 6L6 derived beam tetrode pretty much like the 807,
but with higher ratings and 11 mA/V slope,
anode dissipation 45 W ICAS and anode voltage 1,25 kV. The TT21 is more
common,
and differs only by the filament voltage 6,3 V, the TT22 has 12,6 V. The
KT88 of audiphile fame is a close relative
From 6 TT22's you should have at least 500 W CW output on 500/2182 kHz
if the power supply allows.
Take a look at:

Hope this helps and 73/

Ämne: LF: T22 - Any info ?
Hi folks,
One of the local amateurs detected a MF transmitter on a scrapyard.
It is equipped with 6 T22 tubes from GEC, but we can not find any
details
for that tube.
Any info available somewhere ?
