<p>The low distortion, high power transistor amplifier is based on three chopper circuits each consisting of four transistors connected as two pairs in series, parallel; each transistor having an associated diode. Two chokes connect the emitter/collector junctions to the load via a transformer and to a current monitor. This provides feedback to a two input comparator feed by a pilot signal itself supplying a logic operator circuit and a logic invertor in parallel. Each invertor is fed from a pair of logic AND gates receiving inputs from the operator and invertor circuits and from a switching circuit.</p> |
