So what was the average hfe on the 404s?

Sorry John, I read the post but forgot to reply after I checked another batch of 20

I've got HFE from the last batch of 20 ranging from 53 to 296 with the majority of them being in the 80-140 range (perfect for my needs) with little to no leakage except at the higher gains

I used to get really excited when I would have transistors with no leakage. And then I remembered that most germanium circuits wont bias up without leakage However those transistors will make fantastic Q1s for fuzz faces.

Cool, thanks boss.

Good thing this batch has a wide variety, after finishing the entire lot I've got HFE from 33 to 396 with leakage from 0 to .58ma but most that have leakage are in the .04ma to 0.08ma range.

Cool, thanks boss.

No problem

For anyone looking to try a few of these I'm selling a few that I've already tested viewtopic.php?f=44&t=19689&p=306583#p306583
