Understanding the market

Half of recorded transactions fall between $40 and $75. The full range runs 2.7× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Ask when the unit was last serviced and whether the output devices are original. Bias and DC offset drift with age on solid-state amps. Confirm both channels have been tested under load, not just powered on.

This range reflects 15 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
