Russ, Thank's for reminding me that transistors aren't always the best answer. It is so easy to forget vacuum tubes are still with us. I think I might get further if I treat this problem as similar to that of driving the deflection plates of a CRT. I was getting nowhere trying to find a solution with bipolars or MOSFET's except perhaps as you said, with a transformer.
The Photocond diode is symmetrical and does not seem to need a ground, so maybe a P-P amplifier with tubes is worth a try.
Thanks again: any further thoughts will always be welcome
Brian Hawes
