Condition is unknown, so the price has to stand on the market data, and at kr14,000 it looks ambitious against the SEK comps. With a median of kr4,839 and a 75th percentile of kr8,753, this asks a clear premium over the typical used range, so I’d only pay up if the transformers are unusually desirable, fully original, and the internal build is very clean.
The upside here is the appeal of a Dynaco-output-transformer monoblock: that’s the part buyers care about, because good iron is what gives these builds their value and sonic credibility. If it’s a well-executed amp with known tube complement, quiet operation, and no transformer or power-supply issues, it could be a satisfying project or keeper—but at this price I’d want proof on originality, service history, and measured functionality before considering it.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Dynaco emerged in 1955 from Philadelphia, Pennsylvania, when hi-fi pioneer David Hafler partnered with engineer Ed Laurent to form the Dyna Company. Hafler brought expertise from his earlier Acrosound venture, which produced high-quality output transformers starting in 1950. The duo targeted the burgeoning hi-fi market with affordable, DIY-friendly kits, launching the Mk II 50-watt tube amplifier shortly after incorporation and relocating to a former chocolate factory for expanded operations.
The brand specialized in tube amplifiers that defined its legacy, including the iconic Stereo 70—over 350,000 units sold—alongside models like the Mk III. Dynaco expanded into FM tuners such as the FM-1, bookshelf speakers like the A-25, solid-state amps, and innovative systems like the Dynaquad for simulated four-channel sound. Late-1970s efforts included the Phase III speakers, though the company shifted toward kits and components emphasizing value and performance.
Dynaco holds a revered position as the era's top-selling tube amp maker, beloved by budget-conscious audiophiles for reliable, high-value hi-fi. Liquidated in 1980 after Hafler's sale to a toy firm, its vintage gear remains a collector's staple, with later revivals by Panor Corporation producing replicas for tube enthusiasts seeking that classic warmth and build-it-yourself appeal.
