History: Customer said there had been no HI-FI audio for some time(tuner and play back), when unit went dead, he decided to bring it to me. Power supply is repaired, but no HI-FI audio. When set to HI-FI, the level meter does not indicate any audio. I have audio went set to MONO in play back and EE modes. I reluctantly replaced IC4001, but that was no help. Any one experience this one? Thanks.
