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!

Electronics Projects, Germanium Transistor Amplifier Circuit " audio amplifier circuits, transistor amplifier, " Date 2016/04/22 . Once AD161-AD162 I had an experiment with pair. I still use almost every day. At first I didn’t like the sound, but I like listening to. The frequency of particular speech sounds very clear and is understandable.

(Double or triple resistor value in germanium circuit.) If the circuit has bias elements besides resistors, disconnect them. For example, some germanium circuits include thermistors in the bias network. (These might be in addition to bias resistors.) 1. 1. 2. Circuit blocks. Gain of silicon transistor is way too high.

Additionally, Germanium transistors usually didn't have as much gain as was needed/wanted, leading to circuit design decisions that would be considered really bad today. Germanium circuits are often overly sensitive to Hfe/beta by modern standards. If you are going to mess around with Germanium, build a test fixture like this one.

I have these old Hacker Radios that use hard to locate decent Germanium transistors in the audio amplifiers and so I was wondering if it would be possible to replace with their Silicon equivalents. The ones of interest are T3, T4, T5 and T6, that's OC71, AC128, AC176 and AC128. The supply rails...

Recommended: 40W transistor audio amplifier circuit with PC B. Which this C2, also helps to make the voltage at the emitter pin or the potential voltage at point D more smooth (from Figure 1). We only limit the sum of the feedback. Because in the basic amplifier circuit, High magnification is more important than high clarity.

Too many answers in the thread. Cannot read them all now. THE THREAD IS FOR FINDING GERMANIUM TRANSISTORS. As far as Ge vs. Si is concerned, for any Si transistor, there is a much better Ge transistor for audio in the same class. Therefore, Ge transistors are better for audio. All of their audio parameters are better.
