Large lot of vintage Onkyo receivers and amps

make / manufacturer: Onkyo  These could all use a dusting! Been sitting in my server cabinet for the last several years... Vintage Onkyo TX-4500 mkII (silver face) receiver - I've had this one hooked up recently powering a pair of speakers, some crackling when turning the knobs, could use a cleaning, silver face appears to have some pitting on the "clearcoat", not perfect - $140 (lowered) Onkyo Integra TX-890 receiver - Aside from the dust, both of these Integra receivers are in very good (9.5/10) cosmetic condition. They both power on (see pic), but functionality is limited or inoperable in some cases, so these are in need of a repair. It's a grab bag of what may work or what functionality is broken, so selling for parts and cosmetics only! $100 Onkyo Integra TX-108 receiver - Aside from the dust, both of these Integra receivers are in very good (9.5/10) cosmetic condition. They both power on (see pic), but functionality is limited or inoperable in some cases, so these are in need of a repair. It's a grab bag of what may work or what functionality is broken, so selling for parts and cosmetics only! $140 (2) Onkyo Integra M-504 amplifiers - Had originally dreamed of a vintage Onkyo audio setup, but these gotta go! 1 of these works and 1 stopped working. Both power on, light up, and look fantastic cosmetically. I had bought all of this equipment off of ebay several years ago and I'm very meticulous about cosmetic flaws. working M-504 $500 non-working M-504 $300  Newer Onkyo TX-NR818 receiver - A newer surround sound receiver from 2012. This was one of the last models Onkyo made before getting rid of Audyssey sound processing features. Does 9.2 surround processing with an external 2 channel amp. Includes remote and Audyssey measurment mic. Upscales 1080p to 4k surprisingly.... $200 Also have an Onkyo M-282 amplifier available, was going to keep it, but as I'm typing this up, might as well put it out there if you're interested! Had it paired with the 818...
