6 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
5 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $795 and $899. The full range is tight — lowest to highest is only 1.7×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
What buyers should know
Vintage receivers are usually sold as-is. Ask directly whether the unit has been recapped, whether the lamps and switches work, and whether all inputs and the tuner section have been tested. Original wood cases and faceplates in good condition carry a real premium.
This range reflects 5 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.
