Hi Mike & Jim,
I didn't see this thread before posting a new EC2001 thread. How did you resolve your problem?

My EC2001 bench unit has normal readout, but doesn't heat. The 28V output and on-board regulator seem OK. Do you have a schematic? Just voltage and resistance readings on the base, & EC1201A [or EC1201P] would be very helpful. I may just have heater &/or temperature sensor problems.

Thanks,
Jack_son
