Transistor - 2N404A, Germanium, TO-5 case, PNP

In Stock

2N404A PNP germanium transistors. The 2N404A is used in many fuzz pedals along with other effects. The 2N404A is the same as the 2N404 but with a higher voltage rating. This transistor is in a TO-5 package with long leads commonly found on germanium transistors.

For a lower voltage version of this transistor, see P-Q2N404.

These were different than last time, in a gold package instead. Felt picked thru. Didn't get any with gains over 75. Not worth it imo. Wouldn't have ordered so many if I knew they were different from the last batch I got.
