  • Substitute for 2N306 transistor in the L100 model percussion unit?

    Hi, everybody is there a substitute for 2N306 transistor in the L100 model percussion unit? I need to replace mine because it’s very noisy. It gets quiet when I cool it down whit cooling spray
    Thank you
    Kjell

    2N306
    Similar Tubes Normally replaceable-slightly different:
    SYL1396
    Different maximum ratings:
    AC127

    Base Wires
    Filament Solid State
    Description NPN germanium alloy transistor intended as AF amplifier.

    Taken from any old website, check AC127 that would be my first choice. Assuming the 2N306 is germanium of course.

      You might check the schematics carefully to see if Hammond replaced the germanium transistor with a silicon transistor, along with some slight changes in bias resistor values. I try not to use germanium transistors unless I have to.

      There are several Hammond circuits, especially reverb recovery stages, that started out with Ge transistors and switched to Si with a few circuit tweaks when Si transistors became available.
      I'm David. 'Dave' is someone else's name.

        Some of the Hammond AO44 reverb amps from the M100 and A100 used the 2N306 as David says. I have replaced them with 2N2222 silicon transistors without modifying the circuit. The 2N2222 is cheap and plentiful.
