Hi all on the list:It is a normal solid-state relay. (I am not sure if it is the zero-crossing type... you could check with Hannes.) Other information.... L1 is simply 10m of wire, random-wound. The thyristors are typically 1200V or better, 8A or better (8A is the continuous rating, but these are being used in their pulse rating which is much higher. Since it is only a single pulse, TO220 packages with no heatsinks are fine.) IRF make some nice 1600V TO220 devices at a good price. Frank, I will scan the original DUBUS article in German/English for you... but it can't be until Monday.
