The LM386M-1 and LM386MX-1 are power amplifiers designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output
Low Voltage B+ for Valve Audio Amplifiers

Low Voltage B+ for Valve Audio Amplifiers Low Voltage B+ Audio Amplifier Experiments. It has been commonly assumed that valve circuits require relatively high plate voltages to operate; typically at least 45V, with most circuits operating at 90 to 250V. As has been described several times on this site, this is in actual fact not true. Depending
