germanium transistor redesign

Redesign Germanium Transistor Circuits

Using a silicon transistor in a circuit designed for germanium will be a problem without extensive redesign of the circuit.The voltages in the preamp and driver circuits are too low to damage the transistors so i doubt that there was anything that caused a transistor failure.

Build this 8 Transistor Stereo Amplifier

2021-5-15  The original circuit design for the Stereo Amplifier from Radio Shack used 8 germanium transistors arranged in three stages: Differential Amplifier, CE Driver, and Push-Pull Output. These stages were common in high-end commercial amplifier design so the 8 Transistor Stereo Amplifier project should have earned a lot of fans back then.

History of Brian May’s treble boosters and pedalboard

2021-5-3  Brian May’s Red Special guitar and Vox AC30 sound from the ‘Queen II” album still seems to have the distinctive tonality of an OC44 germanium transistor Rangemaster style treble booster. Unfortunately we do not have any photographs taken of Brian’s original Rangemaster being used live or in recordings with Queen.

Aren't you glad I added cheesy digital effects? “Germanium” is a magical word among guitar gearheads, right up there with “pre-CBS,” “true bypass,” “matched tubes,” “point-to-point wiring,” and “scatter-wound.”. And like those other phrases, it ...

What transistor do you use as a CK722 substitute? -

2010-3-8  Audio-Amp units will work. Which means, just about any Germanium PNP Transistor. will work in place of a CK-722. Most will likely work better, since the CK-722 was a very early, experimenter, low-cost transistor, prior to the designs of better units. 2N404 crosses to a GE-53, which is also a Ge, PNP, Audio Transistor.
