PNP Germanium transistor

AC128 transistors are a popular choice for fuzz and overdrive pedals: used in the right configuration, the performance curves on these selected transistors will give that classic roundness only attainable with original germanium technology.

Originally manufactured in the early 70’s (dated ’72) No Manufacturer name or logo present.

PNP germanium alloy transistor for AF low power amplifier applications.

Dimensions: D. 6 x L. 10mm – Leads 28mm

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large ‘Mispec’ type Co. and have been kept in storage for a very long time (they were made in the early 70’s), they are however unused and in good serviceable condition, the photographs are representative of their general appearance, being of some of our actual stock, and, as with all our products they come with a full guarantee.
