Reports[edit]

  • Onkyo receiver from the mid 90's with powerful power amp solid build quality and great RDS receiving section.
  • The 2 x 120 watts into 8 ohms ( 1KHZ DIN ) stated in the manual are produced by the thick transistors sitting on the outside of the heat sink.

The 4 smaller Toshiba transistors in the middle of the mighty cast aluminium heat sink are for the surround rear and centre speakers.

  • When switched to multiroom, they are switched to a stereo amplifier that can play a dedicated source independently of the other stereo speakers. 2 x 80 Watt sine wave are available. The volume is digital and can only be controlled via the remote control (RC-288 M).

Onkyo untypically is with this equipment a Loudness function. In the age the relays tend to contact difficulties which is noticeable by distortions and sound loss. The 4 original VB 24 MBU relays cannot be opened, so that these must be replaced. The relay Finder 40.52 24 VDC is suitable.

  • The contact legs for normally closed contacts must be cut off, as well as reducing the size of the connections for the control coil.

The housing base plate must be removed by cutting through the thin retaining webs, then you can easily reach the soldering points. Afterwards fix it again with M3 screws. By the way, the speaker terminals are suitable for banana plugs, only the black cap has to be removed. Learning remote control RC 288 M.
