Heathkit AA-181

Sold or Listed Prices

7 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $100 and $170. The full range runs 3.5× 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 7 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is enough to establish a working range, but not enough to be precise — treat it as a guide rather than an appraisal.
