I just ordered new filter caps as well as a new 2N4398. I'll let you know if that fixes things or if I need any more help. I'll make sure to test it safely this time.

Rik, is your crowbar circuit available online in a Gerber file or some CAD file? I'd definitely like to implement that, although I see in the other thread that you haven't put together a reference build as of a month or so ago. Any updates on that?

Thanks for all of the help.
