Desoldered this one from an old project today. Pretty sure I have one more around somewhere. Real mojo.

My little transistor tester is running under 5v but Keen's setup is exactly at 9v using my linear power supply. Wouldn't that affect the leakage? Both Keen's and Tran tester get the hFE very close.
I tried doing the Keen method and got confused to the point where I look at the spec for the transistor and if it falls within that range, I just use it—not scientific, not best practices, I'll grant.
My tester which does Ge doesn't even show all the specs of what you've got, and my T7 won't do Ge at all.
This post on audiokarma goes into some detail about different types of testers. The Peak Atlas, of course, are the most thorough when it comes to transistors.
Although if yours is showing more, maybe the leakage current is accurate, at least for our purposes—someone on DIYSB laid it out:
ICE is indeed collector-emitter leakage (I=current, C=collector, E=emitter)
"o" (0?) means base is open
"s" means base is shorted

Hmm, that is a weird one. Have you checked that the LFO is working properly? Scope would be perfect for that.

Yep, looks like he has a 220n instead of a 240pf.

Thanks Brian, Now I just need to figure out why the BBDs are motorboating. Audio gets there and then putt putt, putt...out of the chips. Voltages were looking good but my VOM finally gave up for no reason other than age.. Tomorrow's a new day...
