My Antique Electronic Collection
I enjoy collecting all kinds of electronic things, especially chips, transistors, diodes, vacuum tubes and instruments. Some of my collections have witnessed the development of our country’s electronic industry, even a small diode emits the scent of history.
Instruments
OOps!
Integrated Circuits
- AD667, AD0809, AD1674, AD565
- ADI’s HAS-1202A
HAS-1202A is ADI’s 12Bits Ultra-Fast Hybrid Analog-to-Digital Converter. Its conversion time is 1.2us with an accuracy of 0.012% of F.S. Interestingly, it doesn’t have a track-and-hold circuit, so it must be used with an external track-and-hold chip, like HTC-0300.
- 5G23A and FC3B
5G23A and FC3B are integrated operational amplifiers made in China in 1977 and 1981 respectively.
Vacuum Tubes
- FD-422
- FU-29
- 6P12P
- 6Z19
- 6U1
- 6N3
- 6N16B
- 6J1
- 6P9P
Transistors
-
3AX61
3AX61 is a germanium PNP mid-power transistor. It is made in 1975, Suzhou, China.
-
3DG130
3DG130 is a silicon NPN mid-power transistor. It is made in 1989. In the past, this model of bipolar transistor were often used in radio and audio amplifier.
