This is the fee to have germanium transistors tested for gain and leakage. 1 Original Russian made MP20A PNP Germanium transistor. Similar to AC121 or AC128. These are known to have VERY low leakage and were made for the Russian military. Gains on what I've checked so far are between 50-150. 1 Original Russian made P29 PNP Germanium transistor.

THE THREAD IS FOR FINDING GERMANIUM TRANSISTORS. As far as Ge vs. Si is concerned, for any Si transistor, there is a much better Ge transistor for audio in the same class. Therefore, Ge transistors are better for audio. All of their audio parameters are better. Most importantly, their Ube is more than half of this of Si.

It's hard for me to think of any advantage a germanium transistor would have over a silicon transistor in an audio application. But I can sure think of a lot germanium drawbacks. The 4010S had, as I recall, a lot of noise selected germaniums in it.

Replacing Germanium Transistors - Antique Radio Forums

The amp in the jukebox I'm restoring has 2 germanium transistors on the front end. One tests ok on my cheap Chinese component tester, but the other tests bad. I want to replace both and I'm looking for recommendations. I can get the originals (2N591) for less than $20 with shipping so that seems like a reasonable solution.

I have these old Hacker Radios that use hard to locate decent Germanium transistors in the audio amplifiers and so I was wondering if it would be possible to replace with their Silicon equivalents. The ones of interest are T3, T4, T5 and T6, that's OC71, AC128, AC176 and AC128. The supply rails...
