Class-A power amplifier (1)
The power amplifier presented is a revamped version of the LFA-150 we published in late 1988. It provides rather less power than its popular predecessor, but retains its class A quiescentcurrent setting up to -3 dB below its clipping limit. The aim of the design was to find a good compromise between class A quality and the dimensions of the necessary heat sinks.
