Uce 70V with a Rbe of 30 ohms at least thats what the datasheet states (yep thats right none of that low residual current silicon rubbish). I couldnt find ANY high power germanium amplifier schematics.

WebNov 22, 2024 · 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. Webge transistor datasheet - mp40 ME139.

Remember that the collector capacitance is not usually quoted at Vcb=0, but SPICE needs the zero bias value. As a start the power law could be taken as the theoretical square root but tends to be below 0.5 on many Si devices. csef education.vic.gov.au
