Please,
Keep it simple ( kiss principle).
1. Find a suitable audio amplifier you like.
A Bogen or similar PA amp should be fine - give yourself some headroom
by haveing 25 % more audio power available than you need.
2. Find either :
A. an audio transformer which either will match 4/8/16 ohms on one side
to 600 ohms on the other
OR
B. An audio output transformer which will Match the Plate to Plate Z
of the Audio Output Tubes and provide 600 ohms output.
* NB... in either case.. chose the frequency response you can live with
( 100 cps to 5000 cps should be fine for ham work )
and the power level as noted in 1 above.
If no body will sell you a 600 z audio transformer... I will.
