I bought this pioneer amplifier (SA-408, similar to the SA-410, I guess), but it has two big problems:
1. when I turn up or down the volume, it makes this really nasty noise
2. it seems that it can't reproduce the left channel, as the whole "RCA lefts" seem to be dead (only the "RCA rights" can reproduce any sound)
Can someone tell me what I can do?
Thanks in advanced
