Answer
Dear Felix,

This is a very old receiver. It could be that the 4-ohm load is taxing the surrounds--the receiver only puts out 25 wpc to the surrounds, but the receiver should compensate for that. I suggest trying a pair of 8-ohm speakers (borrow some from a friend). If that doesn't work, the surrounds are malfunctioning, and you need to have it serviced by a professional.

However, before you do that, consider that the repair cost will likely be greater than the value of the unit. You might look into simply purchasing a new receiver. Both Sony and Panasonic make very good models for $200US, which retail actually for less.

Good luck. And thanks for choosing allexperts.com!

Kindest regards,

Kevin
