AD162 Germanium Power Transistor – Vintage Audio Output Stage Excellence

The AD162 is a legendary PNP germanium power transistor, essential for the authentic restoration and operation of classic push-pull amplifier output stages. When paired with its NPN complement (AD161), it delivers the signature warm, natural tone that defines vintage audio gear from the golden age of transistor amplification.

Functions & Applications

Germanium Junction: Delivers the warm, natural midrange character prized in vintage audio circuits.
Push-Pull Complementary Pair: Designed to work with AD161 (NPN) for distortion-free output stages.
TO-66 Metal Package: Excellent heat dissipation and mechanical robustness for power applications.
Restoration Grade: Ideal for authentic repair and rebuild of classic amplifiers without compromising original tone.

Frequently Asked Questions

Q: Should I replace the AD162 alongside the AD161?
A: Yes, in push-pull circuits it is strongly recommended to replace both transistors as a matched pair simultaneously to maintain balanced biasing and avoid crossover distortion.

Q: Does the AD162 need a heatsink?
A: The TO-66 package includes a metal tab for mounting to a heatsink. For audio power stages, a heatsink is recommended to maintain thermal stability and extend transistor life under continuous operation.

Notes

Vintage germanium transistor; NOS stock may exhibit significant parameter spread. Recommended for restoration of 1960s–1970s audio equipment. Always pair with matched AD161 (NPN) for optimal performance.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
