Both valves the same power out but different H voltage, TT21/6.3 TT22/12.6
Used in class C with high voltage,  efficiency 80%,  this rivals the class D es E. Maybe valves/tubes are the way to go especially if you have a good stock, also more rugged and less likely to be Zapped by mismatch etc
But watch out High Voltages and not recommended for Appliance Operators

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

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

Don't  know Mal ,   but  those  TT21's   if mullard are   worth  more than the  TX !

Talking about valve transmitters.
Does anyone recognize this MF VALVE transmitter, One OSC valve, one Stabilizer valve, 2 PA valves and 2 Modulator valves
