Thanks Pete,

I am thinking the 4007 parts would be good myself. I was gonna stick
one in each half wave, but after hearing the CER73 part is 1kv, I'll go
with two in series. I got some MUR1100 parts here but I've had
problems with fast diodes snapping themselves into oblivion.

TX is back on the shelf till I get some more parts.

regards,
Bob
