Both valves the same power out but different H = voltage,=20 TT21/6.3 TT22/12.6

But watch out High Voltages and not recommended = for=20 Appliance Operators

Well  TT22  , lower power  version  I=20 think,   but  still  well  sought   = after  by the  valve-audio  gang  ! 
 
Its  costal   MF RT  ? top  band  = , =20 would  make a  good   160  linear  , = big =20 push to 500  I would  say ?
 
from what  I have  seen , best way  for  500 = is =20 solid  state , cheaper + safer

The valves are 4 x TT22 plus the osc es reg = (B7G es B9A=20 type) Aluminium water proof case, sturdy well built.
Ref on front is type NS6MS, cannot see any = manufacturer=20 name
This TX is in good condx with all Xtals. = This TX=20 could easily be shifted to 472 Khz

Talking about valve = transmitters.
Does anyone recognize this MF VALVE = transmitter, One=20 OSC valve, one Stabilizer valve, 2 PA valves and 2 Modulator=20 valves
ex Ship MF transmitter CW es MCW es  AM = modulation
