Hottop told me they have tested the unit to 130V, line input. The
concern in going any further would be the electronics. Given what you
have done, I should think there would be no problem cranking up the
voltage on the element to get down to 10 minutes. Ever tried that?
I'd like to be at about 10 minutes for 225 gm batches.

I've had cranked it up as far as 132V and regularly hit 130V with no ill
effects after more than three years of running it this way on a regular
basis. But that's me; YMMV...

My shortest roast time so far was about 11 1/2 minutes with 1st crack at 9
minutes with a 150-gram load. First crack will often come at 400F dead nuts
on my Omega TC probe that I've been using for about 2 years.

Is that "cranked it up as far as 132V" at the plug, or have you isolated the heater, and sent 132V to only the heater?

I wouldn't mind shortening, and intensifying the roast, but if I have to cut the load down to 150 grams, I might as well stay with my Poppery.
