Harvey Mayer 100AR, 50AS, 30AT solid state amps.
Made and sold in Mont Albert/Surrey Hills, Melbourne.
Spotted these in the wild. A bit like an ancient PCL-25, using the Audax bextrenes Dunlavy liked to use in his late 70’s and 80’s designs. Wouldn’t be a Duntech without a first order crossover, a time-aligned baffle—and felt.
