I have often wondered why we don't see med power transistors as input devives in microphone preamps. Things like the easy to get in the USA devices like TIP 29s, 30s,etc and they don't cost much.
FWIW I have used tip29s as the transistor in Rangemaster type treble booster for guitar. Less noise and less gain this can be a good thing. The die is bigger so they could have less noise. I am thinking of trying this with an AMEK 2500 type circuit. I would use 2 devices and not the 8 smaller ones.
Now for output devices why do people use MOSFETS instead of Bipolars for output devices I does not make sense to me. Maybe IGBTs make sense.
PRR posted at the old TT a simple SS microphone pre Altec? I wonder how power devices might work in that circuit.
