A few years back I started a thread about my Sansui 9090db. http://audiokarma.org/forums/index.php?threads/lightning-damage-to-9090db.437704/page-2 I had it fixed and recapped by an AK member back then. I tried to call him a few times over the past few days, but he has not responded so I suppose he is not interested and I have to find another alternate. Since it was recapped, it has worked fine and sounded great, but dirty pots developed (sooner than I would have expected) which were annoying. I was always able to regain signal by working the switches. A few days ago, I was working the Dolby switch - then the sound simply disappeared (there is a very slight sound if I turn the volume all the way up). I am hoping this is not the dreaded Dolby board issue. I need to find a technician in Des Moines, Kansas City, or even Chicago (I travel there frequently enough). I am guessing this repair is well beyond my abilities. Thanks.
