Re: SOLVED - ProgRock Preliminary Test Failure

Eric,

- using my TC-1 Multifunction Tester. It tested good although the HFE was higher than I
expected. It was 390

I found the same here. Transistors which tested an HFE of 200 on a cheap DVM, measured about
400 on a TC-1. A HFE of 200 was within the specifications of this particular device, 400 is
not.

So, I gather something is amiss with the HFE measurement of the TC-1.
