Hey
I've got an old reciever which while not very nice to listen to would be a shame to throw out. I've been quoted $150 for the repair, but i'm a bit too cheap for that.
Basically the connection is very intermittent. There's nothing i can do to set it off, but there is something I can do to bring it back to normal.
In the 5 channel prologic 2 decoder it's only the front L/R channels which intermittently frissle out with a nice scratchy sound.
It only happens at lower / ish volumes.
It happens mainly in summer.
It fixes itself when i turn up the volume and turn it down again.
Now my guess is somewhere on the output of the amp (oh it's got 2 massive Class-B amplifier chips which do the work), there's a solder joint which isn't to happy to have low levels of current going through it, however is still happy when the volume is up a bit. I've excluded the volume control as the source of the problem since if I turn my source down and my volume up, the intermittent connection still occures. The fact that only the L/R channel do it leads me to believe that the prologic / input / other assorted decoder stages in the amp can be ignored.
Is this a likely situation? Is it possible that I could fix the problem by running my soldering iron over all the soldier joints I can see in the relevant areas?
Incase it matters it's a Sherwood RV-6010R prologic reciever.
