Found in a 1964 Electronic Design this transistor limits signal amplitude to a load. The output is limited to 0.2 V using germanium diodes.
This circuit, obtained from a 1965 magazine, can still be assembled using some modern equivalent...
Other series amplifiers such as the MC3301, MC3401 and LM2900 can be used on this circuit. We...
