mosfet gets "stuck on" when using project volatage but not external voltage for dc-ac inverter

Entertained your request and moved the cap from where it was to put it across the transistor emitter (negative power rail) and the positive rail
Doing that introduced the old issue again. So putting the cap as close as possible to the inverter fixes the issue.

One thing to note, I found that using the new working circuit with the cap directly on the inverter....if I took the same cap, and simply moved it 2 feet away using alligator clips it no longer worked - physical distance is clearly also a factor in eliminating the noise. The closer the cap to the noise...the better.

One again - thanks!
