The AF126 is a vintage PNP germanium transistor in a TO-72 package, engineered for IF (intermediate frequency) amplification in AM/FM radio receivers. A direct, whisker-resistant successor to the AF116, ideal for restoration and vintage radio projects.

 

AF126 Germanium PNP Transistor – Vintage Radio IF Amplification & Restoration

The AF126 is a classic PNP germanium transistor purpose-built for intermediate frequency (IF) stages in vintage AM/FM radio receivers. As a direct, whisker-free replacement for the earlier AF116, it combines the proven electrical performance of its predecessor with modern, reliable packaging that eliminates the tin whisker shorting failures that plagued older stock.

Functions & Applications

  • Germanium Junction: Low forward-voltage drop (~0.2V) ensures excellent gain and minimal signal loss in RF/IF circuits.
  • Direct AF116 Replacement: Identical pinout and electrical characteristics, but in a whisker-proof TO-72 can.
  • Vintage Radio Restoration: Purpose-designed for AM/FM receiver IF stages, mixer and oscillator circuits.
  • Reliable Packaging: Modern manufacturing eliminates tin whisker formation and the reliability issues of 1960s stock.

Frequently Asked Questions

Q: Can I use AF126 as a direct replacement for AF116?
A: Yes, the AF126 is pin-for-pin compatible with the AF116. The main difference is the TO-72 package, which has a smaller diameter than the older TO-7 can, and it eliminates tin whisker failures. Electrical performance is identical.

Q: What makes the AF126 better than vintage AF116 stock?
A: The AF126 uses modern, whisker-resistant manufacturing. Old AF116 transistors in original TO-7 cans are prone to tin whisker growth inside the sealed can, which can short internally without warning. The AF126 eliminates this problem while maintaining the same circuit performance.

Notes

Vintage germanium transistor; NOS (New Old Stock) or vintage restoration part. Requires careful handling and may exhibit slight parameter variation typical of 1960s–1970s manufacturing. Ideal for authentic restoration of classic radio receivers.

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