Tony,
set testing tomorrow on a Pye P114BQ to begin. I was going to go with the thyristor type of crowbar, as the sets I have are only 1.4v heaters I was going to put a crowbar on that side to begin with and expand from there as and when.
I thought about 2v for the zener, but did not realise that may be the lowest voltage!
cheers Mark
