Roguedog, Derfly,

Yes, the power supply is working now. The solution was to increase the value of the switching capacitor from .22uF to two .68uF cap in parallel. That's what it took to get the triac to switch on early in the phase. Now it heats up my 36" bow quite convincingly. Now to cut some cores....

Derfly, your supply is very nicely built.
