RE: Heyboer MQ replacement HTS 5504-1

If you don't have a variac, perhaps you have a 6v or 12v transformer in your junk box. Consider hooking the 6v or 12v transformer primary leads up to the 120v mains, and do all your testing with the 6v or 12v outputs as the source for your Heyboer testing. Though you have to do a bit more math, this makes the whole operation a lot safer.
