Beetle - how did that Halcro amp weather the ages? Its circuit topology seems reminiscent of the BM AHB-2 in layman's descriptive terms.
Indeed specs don't tell the whole story and harmonic distortion can be a particularly beast since low / even harmonics sound sweet and odd and highers sound non-musical.
