This 80's circuit uses an audio amplifier to obtain a symmetrical source from a single source. The maximum current is on the order of 1.3 A and the input voltage must not exceed 20 V.
The purpose of this circuit is to convert a rectangular pulse into a sharp pulse for triggering an SCR. The...
In reality what we have is a microphone amplifier that works with 4 batteries and a magnetic...
) These two circuits were obtained in a 1977 Radio Handbook. The transistors are from that time,...
