If it is a vintage unit, probably your best bet is to purchase a service manual via ebay or sources listed in this forum and find someone local. If near a major city, call the local broadcasting station, preferably television, and ask them who fixes their equipment.
Thanks. Found a guy who is an authorised agent for Sansui, does that mean he is an authorised repair guy ? Dunno. Will find out soon enuf. Oh, and it's not a vintage unit, just ol' trust worthy A-9.
