Hi,
I recently acquired a 771 in need of a little TLC. This receiver completed the series in my collection - 331 through to the 881 (we didn't get the 221 over here). It was stated as having low volume on all inputs, and was in need of a good clean. Once I had it opened up on the bench, a quick diagnosis showed that the only thing wrong was an intermittent source selector switch, a little di-oxit and the problem was resolved. She was a little dirty inside, but underneath the layer of dust and hair she is in pretty good condition.
