Questions about Fuzz Face / testing NKT275

Not open for further replies.

Hey guys, I'm new. I live in the USA, and go to school for electrical engineering at carnegie mellon.

Questions are:

1) How do I identify the collector / emitter on an nkt275. Can't seem to find it online.

2) Why don't I get reasonable leakage values when I try testing them as suggested on the famous "The technology of the fuzz faec" article. I will link. No matter what I do I cant seem to even get more than millivolts running through the 2.8k ohm resistor. PLEASE HELP!
