Dave, are you quoting Lorenfb there?
To be fair to OP, it seems like he was following the parts list in his first post link to (the late, and highly respected) Warren/Early S Man’s thread, which has part numbers that align to the required component specs, definitely worth a read if you have not done so already:
He used a thyristor that meets spec (and is the main controller of current in the circuit (800V / 50A) vs transistor 1 (250V / 40A).
So i feel like he’s done a pretty decent job of problem solving on this one - especially for a first time poster! Who knows, it might be him helping us figure out a thorny problem not too far down the road…
