Hey Marshal

Its a DC blocking capacitor that should stop the heavy DC currents from flowing at the rather low DC voltages that the GDT sees. If you have problems with lower values, try using a larger, up to some uF and with a 100nF in parallel, this should take care of resonance in the GDT primary drive circuit.

I am wondering, what is c4 for in the schematic, is it a dc blocking cap or it it used for something else?

Hey Daniel

I am only working with his universal driver as Steve called his own older designs for obsolete compared to the new driver.

I wanted to ask you what you think of Steves DRSSTC schematic with the flip flop circuit, so that the interrupter never shuts off the UCC’s. I came up with a way to use another 555 with the feed back as part of its timing instead of the 74HC109.

does it actually need a “flip-flop” device? because some times the output wont line up and will send out a very short on time
