Product Details

AF106 Germanium Transistor – VHF Tuner & RF Mixer Classic

The AF106 is a vintage PNP germanium transistor engineered for high-frequency RF applications. Its low noise and excellent gain linearity at VHF frequencies make it indispensable for restoring classic television tuner stages and FM radio circuits. The TO-72 metal package with internal shield ensures reliable performance and minimal crosstalk in sensitive tuning networks.

Functions & Applications

VHF/UHF Optimized: Purpose-designed for oscillators, mixers and RF tuner stages in vintage televisions and radios.
Low Noise Germanium: Excellent signal purity and minimal distortion in high-frequency RF circuits.
Shielded TO-72 Package: 4-lead metal case with internal grounding shield, ideal for RF applications requiring isolation.
Vintage Restoration: Perfectly suited for black-and-white TV tuner repair and FM receiver restoration.

Frequently Asked Questions

Q: What is the complementary NPN germanium transistor for the AF106?
A: The complementary NPN germanium transistor is the AF105. Both are matched for VHF tuner applications.

Q: Can the AF106 be used in modern circuits, or is it only for vintage repair?
A: While primarily used in restoration, the AF106 can work in modern RF circuits if proper biasing and impedance matching are applied. However, silicon alternatives like the 2N2219 are recommended for new designs due to wider temperature stability.

Notes

Vintage NOS (New Old Stock) germanium transistor. Characteristics and tolerances vary significantly with manufacturing lot and date. Test in circuit before critical applications. Susceptible to temperature drift – typical gain can shift 0.1%/°C.

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