The Therapy is a departure from what Dr Z Amps has done in the past. We started with a clean sheet of paper and a fresh sonic perspective. The result is a cathode biased 6L6 based amp with a flavor of a low powered tweed Twin. It has a range of tones that will appeal to a wide audience and it includes a special design post phase inverter master volume which does not lose top-end definition at bedroom settings. Its output is a cool 35 watts with a tube rectified power supply. Hand made in the USA.
