Russian Gold
These Russian Germanium transistors are pretty amazing. None of them register any leakage on my meter. I've never come across Germanium transistors with no leakage before.
On the right is an MP39B and on the left is a GT308V. This is the pair of transistors used in the Joe Bonamassa Fuzz Face pedals.
The MP39B transistors seem to be testing out at around 40-50 hFE. The GT308V are all around 60-80 hFE. So ideal for a low-gain Fuzz Face that will work with humbuckers. No wonder they chose this pair for the Joe Bonamassa Fuzz Face.
You know, these date from the 1990s. Most of the world stopped making Germanium transistors in the 60's. So that may have something to do with why these are built so well. They're from the very sunset of the age of Germanium transistors.
