Hello good people. I have Pioneer ct-w803rs double deck, which war recording just fine for several years but several days already on both decks recordings are two bars lower in volume according to level meters on the deck itself. Old recordings are good I checked levels are fine. I tried recorsing on both sides results are the same one channel 2 bars lower. What it could be? If it is on both sides yhen something is wrong with recording schematics? Maybe capacitors are going or something?
