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 circuit periodically reverses the rotation of a motor to change the position of eggs in an...
This ouput push-pull stage using bipolar transistors was found in a publication of the year 1968....
With this high voltage regulator, we can obtain 100 V outputs with currents up to 400 mA. The...
