AC152 PNP Germanium Transistor - Vintage Amplifier Restoration & Audio Repair

The AC152 is a PNP germanium transistor essential for authentic restoration of classic European amplifiers and audio equipment. Its warm, low-noise characteristics made it a popular choice in vintage AF (audio frequency) amplification stages throughout the 1960s and 1970s, and remains highly valued by vintage enthusiasts and audio engineers.

Functions & Applications

Vintage Germanium Construction: Authentic reproduction of original 1960s–1970s specifications for period-correct repairs.
Low-Noise Audio Grade: Ideal for pre-amplifier and AF amplification stages in classic tube and solid-state audio equipment.
TO-1 Metal Can Package: Robust, thermally stable housing typical of professional audio and industrial applications.
PNP Polarity: Direct replacement for original circuits designed around PNP germanium amplification stages.

Frequently Asked Questions

Q: Is the AC152 suitable for new circuit design or only for vintage restoration?
A: The AC152 is primarily recommended for authentic vintage restoration and repair. For new designs, modern silicon BJTs like the BC557 (complementary PNP) offer superior reliability, lower cost and wider availability.

Q: What is the complementary NPN germanium transistor?
A: The complementary NPN germanium part is the AC151. Together, AC151 (NPN) and AC152 (PNP) were commonly paired in push-pull audio output stages.

Notes

Vintage/NOS germanium transistor. Essential for authentic restoration of classic European audio equipment. Check circuit documentation carefully before substitution with modern silicon parts, as germanium's lower Vbe (~0.2V vs 0.6V for silicon) and different temperature coefficients may affect bias conditions.

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