US$76 looks like a fair-to-good buy if this is the vintage TX-810, and a strong buy if it’s the later TX-RZ810 class receiver. Comparable used examples I found for the TX-810 vintage amplifier cluster around roughly US$80 to US$120 when tested and complete, so US$76 is solid rather than flashy; for the RZ810 family, typical used prices sit much higher, making this listing look like a bargain if that’s the actual model.
What makes it worthwhile is the usual Onkyo appeal: clean, no-nonsense build, good phono-friendly vintage charm on the older TX-810, and enough classic two-channel muscle to make a modest system feel composed. At this price, the key upside is simple: if it powers up cleanly, switches quietly, and includes the essentials, there’s real value here. If it’s the vintage unit, confirm the controls are quiet and the channels are balanced; if it’s the newer AV receiver, verify HDMI and all zones before buying.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Onkyo traces its roots to postwar Japan, founded in 1946 in Osaka by Takeshi Goda, an engineer at Matsushita Electric who envisioned high-quality Japanese loudspeakers. Initially established as Osaka Denki Onkyo K.K., the company began production in 1948 with the acclaimed ED-100 speaker featuring a 25 cm driver, quickly building a reputation through LP concerts and innovative designs that resonated with audiophiles.
The brand excels in premium home audio, renowned for AV receivers, hi-fi amplifiers, and surround sound speakers that deliver exceptional clarity and power. Its portfolio spans turntables, DACs, headphones, and cables, bolstered by acquisitions like Pioneer's home electronics division in 2015, enabling cutting-edge integrations such as internet radio and high-resolution streaming.
Onkyo holds a solid mid-tier position in the hi-fi market, prized by discerning buyers for reliable performance and value rather than ultra-high-end exotica. Despite bankruptcy challenges in the late 2010s, its revival under new ownership preserves a legacy of technological innovation and pure sound enjoyment, appealing to both vintage enthusiasts and modern home cinema setups.
