Re: Recent s.s.t.c. work

Just to assure some of you that I've not totally given up yet...

As I've mentioned before, I find that at my advanced age I'm losing the motivation to continue "making things"--as I have been doing for ~70 years. So I haven't done anything further yet on trying to find the source of the problem with my new s.s.t.c. I think that I have set the peak gate voltage too high, and consequently shorted the gate of one of the bricks. I can readily reduce that by 5V and I have 2 more good bricks; it's just a matter of getting around to it.

Finn Hammer mentioned potential problems with putting the primary inside the secondary, as I have done. I think my solution to that would be to raise up the entire secondary so that the bottom of it was more or less at the top of the primary winding. Then, add an auxiliary secondary, of sufficiently larger diameter, aligned with the primary and of more or less the same height. That way, I keep all the existing hardware and only have to fabricate the relatively simple auxiliary coil and its former.

So the steps I need to take are clear. I'll likely get to them some time after the holdiays are over.
