Default Re: Transistors wanted

I have tried a couple of silicon transistors in other circuits. Sound great. But germanium has a distict tone to it. Kind of like tube vs transistor amps. Germanium adds a warmer tobe and you can roll off the volume without it sounding harsh. A great warm tone. I measure the transistors using a transistor tester.

What i like to see is a hfe of about 120 and leakage under 300 ua. Never had any luck with npn transistors. They're usually way too much leakage to them. Making impossible to bias correctly.

Pnp transistors is way better in leakage.
Cool that you built that treble booster for him leading into thst song. I have to check it out. But I bet it sounds cool if it's like them. The best Van Morrison has done ever in my opinion.
