Audio preamplification transistors ex : NKT275 (Fuzz Face, 1966-67) These are the most common germanium transistors. They were designed for audio pre-amplification circuits in consumer and mid-range equipment, where they quickly replaced the tubes. They are distinguished by a gain which can reach 200, and a maximum frequency of the order of 1MHz.

Germanium Transistors Preamp Schematic. Last Updated on Wed, 21 Jul 2021 | Radio Amateur 03-1967. HIGH 5k. Fig, 18- This phase splitting circuit provides two out of phase signals for driving a push pull amplifier without an expensive transformer, The gain of the stage as shown is 150, but this may be adjusted by changing the value of the 22K feedback resistor.

Death By Audio Germanium Transistor Distortion/Filter Pedal. TRUE VINTAGE DISTORTION. The Germanium Filter is our love letter to sticking a pencil in your speaker. Start with a console-style drive circuit, add in a dash of obsolete germanium transistors, and finish it off with a super intense DBA-style filter, and BLAMO!

I don't know about the IF section, but my LTspice simulation shows that you could happily change all the GE transistors for silicon ones in the audio amplifier circuit with no necessity to change any resistors, the only adjustment needed being RV3 (and possibly RV4) to set the output stage bias and, by virtue of the DC feedback loops, the bias of the other stages. …

First, enter the power supply to the circuit and the audio signal to the input terminal. Then, the audio signal coupling to through the C1 and R1 to amplifies by transistor-Q1. Which the Q1 is a first Preamplifier to increase a little signal up. Before sending it to Q2. Next, the Q2 is connected to the emitter follower circuit.
