Quad 33/303 erratic behavior
I wonder if anyone has any insight into this problem: my Quad has the most wonderful sound when I turn it on, but then the sound inexplicably becomes soft and filled with static. If I unplug the power lead from the back of the amp and then plug it in again the problem is corrected for a short time, but recurs many times. After a while this misbehavior seems to stop. I have had the unit at a local Quad "expert" several times, with no success in resolving the problem, even though he states that he replaced all connectors.
Any help will be greatly appreciated.
