Frequently Asked Questions

Q: Is the AF186 still suitable for modern DIY RF projects?
A: Yes. While originally designed for 1960s–70s TV tuners, the AF186 remains excellent for vintage radio restoration and retro RF amplifier projects. Its low noise and stable gain make it reliable in fixed-frequency or narrow-band applications.

Q: What is the complementary NPN germanium transistor?
A: The complementary NPN germanium transistor is the AF185, offering matched electrical characteristics for push-pull or complementary RF amplifier stages.

Notes

Germanium transistor: vintage NOS stock. Requires careful ESD handling despite germanium's natural immunity. Not suitable for high-temperature applications (Tj max ~100°C typical). No longer manufactured; collector's and restoration item.

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