Bullet proof unit. Still have mine from 1975. Other than changing a few dial indicator lamps and cleaning the pots and switches it works flawlessly. Always sounds great!

Great little receiver, especially at the price you can find it for--a fraction of what you'd pay for a comparable Marantz, and cheaper than Sansui and Pioneer. It's the equal of any of them (I've owned them all). The TX-2500 has a great tuner and every feature you'd expect in a small receiver. Its amp section, which seems to put out more than its power rating, has plenty of detail and some warmth in the sound. An audiophile piece? No, but it's a great value in its category (25-30 wpc vintage receivers). It looks nice, too, especially when lit up at night.

Found a TX-2500 last fall at a local Goodwill for $10. A little homey looking (my original receiver was a MK II back in 1980) and expected it to be a weak performer based on power specs. Cleaned the controls and was surprised how well it sounds and tunes for a lower end receiver is working well with a refoamed pair of Advent Baby IIs found later at the same GW and a powered subwoofer. It impressed and has won me over. Should work well for a small to midsize room with a pair of efficient bookshelf speakers like the Advents. These vintage Onkyo receivers are not small or light. Much larger than a similar Technics SA-5170. Surprised by how cool it stays at 40-50% volume.

A workhorse. I acquired one that had been playing everyday for over 25 years and the thing is still going. The business I bought it from is gone and this thing lives on. Great entry level receiver with proven longevity.

Very good replication of sound, stage is O.K. tuning is kind of novel with touch tuning integration. All in all for 1977-8 this is an average machine, I really do enjoy the lamps at night time if you do get this make sure it rests near a wall as the lighting comes up through the cooling grates and gives it a 2001 Space Odyssey Hal Computer effect!
