We found this circuit in a 1977 documentation. The National Semiconductor's LM380 is no longer easily found, but if used on this amplifier it provides excellent reproduction quality.
This is one of the first circuits published on this component. We found it in the September 1950...
Found in American documentation from the 90s, this circuit uses a high voltage relay and has no...
This circuit generates high voltage pulses, which can reach 30 000 V with the discharge of a...
