This circuit was found in a 70s documentation. The transistor is from that time. L1 has 4 turns of wire 20 in the form of 3/32 inches and L1 has 10 turns of the same wire,
This circuit can generate signals up to 20 MHz, depending on the crystal. The circuit is TTL and...
This circuit is used to test SCRs like the ones of TIC series. The simulation shows the power line...
Here we show an oscillator that uses an LC network. The upper limit depends on the power-supply...
