Hi Group,
  I just picked up a military Redifon HF 125 linear amp and matching ATU
made in the UK. I was told it was made to be driven by 100- 300 milliwatts
with a choice of 20 or 100 watt output. I'm looking for any other spec's,
schematic, ect for it. I know it has switchable filters for between 2 and
30 mhz the filters are meant to be switched with a control cable interface
from what ever exciter was designed to be used with this amp. Anyone know
what set this came from or what exciter  would have been originally used
with it. I'm thinking of getting a little A510  Aussie QRP hf manpack rig
from the 50's to drive it. could be fun on 40m and 80m CW/AM. That way I
could play QRP with the A510  or QRO by running  the amp.

  Cheers,
   John
