Hello I recently purchased a sanyo m-g12 and when it arrived it had no output when playing a tape. I thought it was faulty capacitors so I replaced them all but it maybe helped about 1% since i can hear a faint distorted static sound occasionally, I also re-soldered all points and de-oxidized all the pots and switches. Any advice on what could be faulty? My model also appears to be a revision model since it's made in Korea instead of japan and the circuit board looks different than ones I see online.
