Reports[edit]
- A known malady of this series of Onkyo is a, over time, malfunction of the Input Selector.
- Due to dirt and corrosion within the rotary switch, contact problems are common, resulting in erratic and random jumping around between inputs. However, there is often one or more positions of the rotary switch where the problem occurs less frequently if at all.
- The problem can almost always be eliminated by treating the inside of the rotary switch with contact spray, or better yet, mechanically cleaning the contact surfaces beforehand. A recurrence of the problem after a certain time frame, which can range from hours to years, cannot be ruled out.
When using Contact Spray 60, you should always rinse afterwards (e.g. with Contact WL), as Contact 60 attacks non-ferrous metals!
- Competitors : Onkyo A-8780, Onkyo A-8870, Pioneer A-702 R, Yamaha AX-890, Sony TA-F 690 ES, Denon PMA-1080 R, Denon PMA-1315 R
