Frequently Asked Questions

Q: Is the ACY17 suitable for vintage audio amplifier restoration?
A: Yes. The ACY17 is commonly found in older audio circuits and is ideal for period-correct restoration work. Its germanium characteristics are valued for maintaining the warm tonal quality of vintage designs.

Q: What is the complementary NPN counterpart to the ACY17?
A: The ACY16 is the complementary NPN germanium transistor with matched electrical characteristics for push-pull and complementary output stages.

Notes

Vintage germanium part; NOS and used stock availability variable. Requires careful thermal and bias management in modern designs due to higher leakage current and temperature sensitivity compared to modern silicon transistors.

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