request for a little help with transistor testing

[buildafriend]

A friend and I are making a few fuzz boxes and we wanted to have the power on hand to continue doing so. We bought PNP old stock transistors from around the globe. We ended up with a few hundred of them. Some from the USSR from before the curtain fell, some japanese crap cakes, and other various old stock transistors such as some AC125s. We are using http://www.peakelec.co.uk/resources/dca55_userguide_en.pdf as our transistor tester but it seems to dislike low HFE transistors.

GT313A tests as "three terminal bicolor LED" (this transistor has 4 leads. From what I have deducted from the interwebz the extra pin is just a shield).

GT313B tests as "LED diode junction"

6 out of 50 GT308's tested as "three terminal bicolor LED"

Is there an approach that any of you forum members like to take when testing Ge PNP old stock transistors that does not rely on this modern no brainer transistor toy? Do you have any literature that you would recommend? Thanks regardless.

I use the same device and have never had a problem.  Might be worth speaking to Peak about it in case it's developed a fault - they're really helpful guys.

I knew I'd seen something like this recently... Here's a reply to a similar question from Jez Siddons, who actually works for Peak Electrronic Design.

NewPerson: I was given that link by a good man on the group DIY forums. Thanks very much for also suggesting it.

R O Tiree: That article expressed lots of useful information. I can't thank you enough for redirecting me. I see that PRR is in that thread and I always love his input.

Now the war continues as I attempt to pull information from datasheets that are in russian and to hunt for a datasheet for the tungsram AC125 V.
