Germanium Pnp Replacement

UK Vintage Radio Repair and Restoration Transistor

2012-8-17 · At the time of writing a limited range of germanium audio transistors are still available, but it is probably only a matter of time before they are discontinued. The AC128 is a good general-purpose replacement for OC71, OC78 and OC81. Note that AC127, AC176 and AC187 are NPN and the others are PNP.

TO7 and TO45 are the same case. TO45 is what replacement transistors were made to. For PNP TO45, try the SK3006- I know of no other TO45 cased replacement transistors. ECG and NTE replaced these with the ECG/NTE160, a 4-legged TO72 cased transistor. It's also what most distributors will sell you. SK3006 transistors are still around, albeit scarce.

ac128 germanium pnp transistor All About Circuits

2015-3-21 · I'm working on a guitar pedal that calls for a ac128 germanium pnp transistor and I was wondering why I might not want to just get a modern equivalent. Thanks . Like Reply. Scroll to continue with content #12. Joined Nov 30, 2010 18,167. Aug 8, 2011 #2 It depends on the circuit. Germanium has slightly different characteristics from silicon.

Substituting Silicon transistors for Germanium All

2017-8-7 · I was wondering if anyone could help me locate a way to find substitutions for the following germanium transistors. I'd like to convert a circuit to silicon if possible. I have SK3009, 2N2428 and 2N2431 transistors. Any help would be appreciated. Thanks.

Does it matter if I replace germanium transistors with

2020-1-27 · As to your question, looking at fig 3, 4 and 5 on page 5 of the article, I think you could replace the PNP germanium transistors directly with a small silicon PNP transistor such as BC557, 2N3906, BC328-25, or BC640, or any other cheap small signal PNP silicon transistor, without any changes to the rest of the circuit what-so-ever.

Replacement Transistor The RadioBoard Forums

The AC126 is germanium PNP. NTE 102 is the replacement. Long time ago we would take a 'cheap' transistor radio apart and put two phone jacks in it. We would wire the input to the volumn control and the speaker wires on the output. The local band would buy and put it in front of the guitar amp.

Choosing Transistor Replacements » Electronics Notes

Choose a transistor of the same polarity: The first major selection criterion is whether the transistor is PNP or NPN. Select a replacement transistor of the same material: Most transistors are either silicon or germanium. As bias voltages and other features are different it is necessary to select a replacement transistor with the same material.

2018-2-6 · According to R. G. Keen, the physical characteristics of germanium made it much easier at the time to manufacture PNP devices rather than NPN. The demand for non-leaky, temperature-stable NPN devices of consistent gains was one of the factors that drove germanium

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.

Yes, I too use Russian types. But often the RF & IF can be replaced with PNP Silicon if there is an emitter resistor. Yes, the collector current may be lower, but with suitable gain RF types, it's not a problem. In a Bush set no difference in performance using Russian Germanium or regular PNP Silicon for RF mixer oscillator and the IF amps.
