SSG modes COP

[Dave45]

The triggered pulses are pretty short, 25 ms or so.

Bro I have to say you do good work.

I wonder what "COP" you get in MHOP mode.

Isn't MHOP about how to trigger the switch rather than where the switch (and the rest) is in the circuit?

That's mostly true, although there is a little finesse in the output side as well. But yes, it is still your basic lowside switch arrangement.
The MHOP's sense/trigger system gives the operator full control over dwell and timing, and the optional strobe circuit lets the user know the timing and dwell without the use of external instruments like a scope. The coil polarity can be reversed by a switch, so it's easy to change from an attraction-type to a repulsion-type PM without complicated reconfiguring, and the power take-off and recirculation bits have options too. The recirculation, for example, uses 2 neons, one each to the positive and negative poles of the run battery.

Thanks! I'm learning, right along with the rest of us.

Trying out a variant, seemed like a fun thing to try and make, thanks for sharing TK!
Pic of my (second) attempt; used an LED instead of the diode and I added a 331 potentiometer on the positive input instead of a 330 ohm resistor.

Okay, back to lurking...
