I bought the 8850 amplifier from Onkyo in January 1992 with the DX 6830 CD player, TA 2870 cassette deck, T 4830 tuner, all from Onkyo and Revox loudspeakers, and have had no failures to date. I am more than satisfied!
  
Das Problem lässt sich durch eine Behandlung des Innenlebens des Drehschalters mit Kontaktspray -
 
besser noch mit einer vorhergehenden mechanischen Reinigung der Kontaktflächen - fast immer beseitigen.
 
Ein erneutes Auftreten des Problems nach einem bestimmten Zeitrahmen, welcher von Stunden bis hin
 
zu Jahren reichen kann, lässt sich nicht ausschließen.
 
Der Erfolg hängt stark von der Intensität der Reinigung und der verwendeten Mittel ab.

Reports[edit]

  • A known malady of this series of Onkyo is a, with 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.
