You can follow the signal path through the pcb by following the traces that can be seen through the translucent board. A complete description of each part's function:
1 AC125 PNP Germanium transistor, new old stock, made by Tungsram. They are a direct substitute for OC81d and work great in fuzz pedals. Gain range is 60-130, so they are right in the fuzz face range.
Bipolar junction transistor Wikipedia
A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electrons and holes as charge carriers.. Unipolar transistors, such as field-effect transistors, only use one kind of charge carrier.BJTs use two junctions between two semiconductor types, n-type and p-type.. BJTs are manufactured in two types: NPN and PNP, and are available as

NPN vs PNP Germanium
13/01/2004· A lot of boutique RangeMaster clone builders will have you believe that the only way to get them to sound right is to use one of those "super rare" transistors that have been sprinkled with magic dust by the transistor fairy With all the testing and tuning I've done with the RangeMaster, that just hasn't proven to be true. I've used gain and leakage checked AC128 (PNP), AC188 (PNP

Alloy-junction transistor Wikipedia
The germanium alloy-junction transistor, or alloy transistor, was an early type of bipolar junction transistor, developed at General Electric and RCA in 1951 as an improvement over the earlier grown-junction transistor.. The usual construction of an alloy-junction transistor is a germanium crystal forming the base, with emitter and collector alloy beads fused on opposite sides.

NPN vs PNP Germanium Transistors for a Fuzz Face
13/10/2018· IIRR, I have read somewhere on this very site that the [early?] processes that produced the PNP germanium transistors produced a lower noise part than the processes involved in the NPN production. so they made more PNP's.
What makes germanium pnp transistors ideal for fuzz
r/diypedals: reddit's community for DIY Pedal Builders! My experience has been that pnp germanium sounds better in a fuzz. Can't explain why, but I've got plenty of both and I have built plenty of fuzzes.
Bones Hi Fi: Germanium Transistor Based Audio Power
10/05/2013· And during much of the 1960s, even then commonly available germanium output power transistors – like the now extremely rare AD 149 PNP germanium output transistor which can produced 10 watts in a single-ended configuration if properly heat sinked – remains under utilized by electronic enthusiasts of the day because back then heat sinking
It's Raining Germanium! tonefiend
13/08/2013· PNP are easier to find in the correct hfe and leakage as NPN seem to be hfe high= leakage high. My local electronics place had some great high gain ge pnp philcos, and I bought them all before you all got them. Germanium does sound better in a fuzz face in my opinion, though it depends on your playing style and technique. I have found that NOS

E.S.V. Fuzz Germanium Version – Build Your Own Clone
The original germanium Fuzz Face used PNP transistors and had a positive ground. The silicon version used NPN transistors and had a negative ground. Positive ground means that the sleeves of the jacks, the chassis/enclosure, and ground of the circuit are all connected to the positive terminal of your power supply. Negative ground is the same thing, only everything is connected to the negative

What Germanium PNP transistor do I use? | Electronics
17/03/2007· Germanium transistors were pretty much obsoleted forty years ago, by silicon transistors. There is a far better range of silicon transistors, and generally they have far better specs than germanium transistors. The only reason you'd use a germanium transistor at this time is if there was a specific reason for using germanium. There are still some
