Congrats. Very nice tuner you have there.
I remember when we had one for cleaning in the service shop , after cleaning and adjustments , it gave many High end tuners a run for their Money . Actually it never left the shop , since the owner's son wanted a NEW with rds plastic tuner. Not sansui offcourse. We bought it for the cost of the repair. 80e, back in 1997.
It still plays every single day since then. I stopped by some days ago . Asked to buy it and the guys loughed at me. I wonder why.
Enjoy.
