Hi Adam,
Yes, I had the wrong post in my brain buffer. Thanks for re-aligning my neurons!

Hi Jeff,
How did you determine that those transistors were bad? If you used one of those do-it-all component testers, check again with a DMM or curve tracer. The testers can break down the base-emitter junction and give a false determination. Whenever I see a report of a whole batch of transistors being bad, my Spidey senses start tingling. It can happen, of course, but I see erroneous diagnoses more commonly.
Tom, I had that same thought when seeing Barry Breaux's post this morning about a 465 he's parting out. I wonder if that's the message you're thinking of?

It sounds like Jeff just has a single bad transistor, unless I read too quickly.
