Original poster: "Gerry Reynolds" <gerryreynolds@xxxxxxxxxxxxx> Hi Bart,I have, but then again, I operate right at the edge of dropout (too far after peak). I determined this point not by the "longest sparks" but by using a scope and going for the highest firing voltage. If timing is delayed anymore from this point, the SRSG stops firing and ferroresonce occurs. This point of operation is very sensitive to the variac output since it doesn't take much shifting in the charging waveform to "dropout" when this close to the edge.

Original poster: "Barton B. Anderson" <bartb@xxxxxxxxxxxxxxxx>Possibly Gerry. The closer the alignment, the more phasing will be affected with voltage. I personally haven't found it as a needed adjustment between say 50% and 100%, but then, there are are a lot of variations of rsg's (disk size, electrode size, # of electrodes, speed, voltage, etc..). Some may find more of a phasing variation than others.Take care, Bart
