Phase Linear 201
"New" Phase Linear 201 amplifier prototype. It was developed after Series I and before Series II amps. According to Dean Nissen of PhaseTek this is the only copy ever built. Logically, no technical data is known. The type "201" suggests power ratings equivalent to 200 or 200 Series Two, i.e. of about 2 x 100 watts @ 8 ohms. The knobs and handles were later used in the 400 / 700 / D500 Series Two. Only the power switch was never installed as a standard.
