I have been buying mid ‘70s Sansui units for the past 5 years. So far I started off with a 9090 non db which has been completely restored. Next I wanted an example of an integrated amplifier. Found an AU 7900 with matching TU 7900 tuner. Had both restored. These both sound great. Now I would like to purchase an example of a power amp and preamp. I would like some recommendations on which ones to look for. I like to keep them in the ‘73-78 timeframe. Which ones are most desirable.
