I have a 9090 db sansui, in need of repairs. The audio won't turn down & the fm tuning isn't working properly. I bought it in Japan, 1977. At the time, I spent over 6 months researching & going to stereo shops. Sansui was my favorite, but would have purchased a Yamaha. If you can do the work, or know whom could do it, I would greatly appreciate it.
