I use them all the time for projects calling for germanium transistors. They sound great.

Thanks.....I pulled the pin on 50
I wonder how the hfe's will range ..I was hoping in the lower 100's as most all of the Russian ger transistors have been always in the lower ranges of there spec's

The first lot of 20 that I ordered fell between 50 and 120 Hfe. I haven't opened the second 20 to test them yet.
