This astable multivibrator has an active cycle of 30,000: 1. We found it in a 1970 EEE. The components used are from that time.
This circuit is from a publication from the 50's. Inductive components are critical, and...
This simple two-transistor circuit used transistors from the 60s, having been found in a...
This circuit uses an oscillator that generates a signal of approximately 1450 kHz to test...
