Back in the 90's I bought a new 5.1 surround VSX504S, I didn't need the surround sound features but I liked the 130wpc it had. It made the two JBL L112's I had really hit hard. About a month after I bought it work transferred me to another state, so it all got packed up and sent here. Not having time or space at the time to set it up, it sat in its original box for 20+ years and got forgotten in an upstairs closet.
I dug it out the other day after being given a pair of huge Cerwin Vega D7 speakers.
To my surprise, one channel sounds weak, as if the woofer wasn't working in that speaker, so I immediately swapped wires on the back and the problem switched speakers. Both speakers work fine. If I turn the bass knob all the way back, both speakers sound the same, but when I add bass, only the left channel can make the woofer work and I don't think its 100% either as I would have thought these old CV speakers would be a bit bass heavy and they're not at all. Thinking it may be just the control pots, I dug out a can of Deoxit I had here and opened up the receiver, but after several treatments on all the pots, as well as a good look at all the solder joints there's no change. I also took a good look at all the caps, looking for any leakage or swelling but this thing still looks brand new. It was stored in the original plastic bag it came in, it was even taped shut and packed up just as it came from the factory all those years. Its got less than 10 hours of play time on it back in the day.
I called a few local shops but they said throw it away, its not worth fixing. It was a decent sounding unit back then, it had gobs of power and decent sound. Right now its sounds worse than a $10 transistor radio from China.
Any ideas?
