Ideas wellcome ! :-)
 
 
Don't need the keyer and would use an ICL7667 as dual mosfet driver
For the mosfets what I have here is a couple of IRFP3206
 
I have a linear transformer with 2x24V outputs. Can be good for an unregulated 48V supply
This is what the audio PA is using now

Time for a D class PA  ;-)
Output filter and transformer core is already here, so should be easy to get some 50w or more (10dB)

That sounds good. Can you show a schematic that you want to build up? Which voltage, which FETs, which driver?
