21 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
6 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $640 and $700. The full range is tight — lowest to highest is only 1.4×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
Prices over the last twelve months have held roughly flat, averaging $672 across 4 recorded sales.
What buyers should know
Check whether the unit uses tubes or solid-state gain, and if tubes, when they were last replaced. Confirm all inputs switch cleanly and the volume control is free of channel imbalance at low levels, which is the most common wear point.
This range reflects 6 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.
