Thanks Dillen - had noticed "recap" often while looking through existing threads - sounds very likely the cause, or necessary anyway. I know fuses age sometimes, but obviously unwise to simply replace without checks......... As far as tape goes, problem was poor sound quality due to tape speed irregularity..reason unknown except reported to

Can anyone advise how deep problem might be? Sound went quieter (from mid) and indistinct, then with soft "bump" lapsed into silence while playing aux/CD. Power telltale remains lit, but both channels absolutely silent whatever vol/bal from tuner/aux i/puts, and all to outputs. No obvious external fuse but perhaps internal (o/p) fuse? or power
