This circuit keeps the neon lamp on for a moment when it receives a pulse. The turn on time depends on C. The transistor is of the old type, from the 60's, when the circuit was published.
This amplifier was found in a 1969 Mullard documentation. The circuit uses transistors that have as...
This circuit was developed to test suspect 4001 and 4011 integrated circuits. The circuit is from...
