The thermo fuse for my cheapo coffee pot was about the size of a one amp N1007 diode. Went series with the line voltage input. When the Borg gets finished my WFCO goes in for surgery if I can find that danged post on the forum that has images and values. But it gets a 10-turn pot instead of a fixed resistor. I cannot seem to find that info by searching. Frustrating. The Megawatts are getting heat sinks and fans today. Then le gran assemblie begins. Lots of wire to lay. Good luck with your own search.
Have you tested the device with a DMM and butane lighter?
