Are you after a genuinely useful vintage tuner, or mainly a cheap Proton component? At US$50, this looks like a strong deal if it is confirmed working: observed asking prices cluster around US$95, while a working example has sold around US$35 before shipping. That puts US$50 comfortably in the attractive end of the market rather than merely “fair,” assuming the listing really is the 600T and not an incomplete video-system component.
The 600T is appealing as an inexpensive, period Proton tuner with useful FM/AM functionality and enough rarity to interest owners assembling a matching system. At this money, it makes sense for a second system, workshop, or Proton stack, especially if the display, presets, stereo lock, and outputs all function. Ask for a powered-up demonstration and check that the original controls and interconnects are present; without testing, the bargain depends on accepting normal vintage-electronics risk.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Proton Electronic Industrial Co., Ltd. emerged from Taiwan in 1981, establishing its base in Banciao, Taipei-Hsien, as a manufacturer targeting the U.S. consumer audio market with high-quality components. Linked to Fulet Electrical, which produced notable NAD amplifiers, the brand launched around 1984 to expand into consumer electronics, including acclaimed TV monitors like the 600M and 602M models. By 2009, it remained active, building on a heritage of precision engineering from shared facilities with brands like NAD and Dynaco.
The company focused on premium hi-fi gear optimized for real-world performance, emphasizing tuners, receivers, amplifiers, and integrated systems that drove everyday loudspeakers with exceptional clarity. While not delving into headphones or cables, Proton's lineup prioritized robust playback under practical listening conditions, from radio reception to vinyl and cassette sources, earning praise for its engineering rigor in the 1980s.
Proton holds a solid reputation in vintage hi-fi circles as a mid-tier powerhouse, favored by collectors for its reliable, high-value sound that punched above its price point. Positioned as an accessible alternative to elite brands, it appeals to discerning buyers seeking durable, no-nonsense performers rather than boutique exotica, with ongoing interest in its schematics and restored units.
