A small operation but very high quality repairs on exotic equipment. They fixed my Sansui AU20000 Integrated Amplifier. I have had one disappointment after another since 1985 trying to get that beast fixed. I couldnt believe it when the guys said SURE. And then they did it. I almost cried. I bought it in Germany in 1978. Its been my baby. Ive hauled that thing around everywhere, even though it didnt work and was a 75lb paperweight. They just dont make them that way anymore. Noow, it sounds as good as new... maybe better. Call these guys...see what they can do for your old electronic components.
