After almost two years of pre/pro duties, I put my Pioneer 1014 back as my primary processor amplifer. I have a problem now. The volume through my speakers is very low, almost nothing when I first turn the receiver on. After playing with the volume knob a bit and maybe switching sound fields, I can get it to normal level and it will say there, until I have to turn it on again. Does this mean the amps in the Pioneer have gone bad while they sat idol for almost two years? Please help, thanks.
