I have a Pioneer SX-1050 receiver that I purchased new in the late 1970s. It was in daily use until the year 2000 when I got a surround receiver. It has since been used semi regularly in the basement.
For the last few years when ever I turn it on there is a low pitched rumbling noise in the right channel which stops after a couple of seconds. It doesn't matter what input is selected and I've cleaned the various pots and switches with deoxit.
I've been thinking about changing the two main large filter caps but I'm wondering if the experts here think that would help. I've looked at the caps and they look perfect, no leakage or bulging anywhere.
The receiver otherwise works and sound great, just as it always has. Great low bass and clean crisp highs. In fact I've run speaker wire up from the basement so I can listen to my JBL L-300s using the Pioneer. I have a switch that allows me to switch between my upstairs surround receiver and the Pioneer.
