The Sansui 210 has to be the lowest powered Sansui solid state receiver ever offered. It is clearly an early '70s model and it is as stripped down in features as it is in power. No balance or mute available, just treble and bass pots along with tape monitor and loudness boost switches. This unit was in very good cosmetic condition.
It worked, sort of, on initial power up on the variac, but was very shakey with a channel imbalance and very dirty controls. The tuning capacitor was especially noisy, sounding like raking gravel. Here how it looks with the top off:
This is a two board unit with the upper being the tuner. The Toshiba outputs are mounted on the very simple heatsink mounted vertically just in front of the transformer. In the photo above it runs from the left to the middle of the unit. There is very little power supply capacitance, just 3 1000 mfd caps just in front of the heatsink. The phono section is shielded and just to the left of the internal antenna. The shield was removed when this photo was taken.
I re-capped the entire unit, a mere 36 caps, and spritzed the controls. Voila! The sound was clean as a whistle. While not exactly a power house the amp had lots of life from the positively cute Toshiba output transistors. The FM tuner was surprisingly sensitive and picked up numerous stations without benefit of an antenna. The AM section was decent with the internal ferrite antenna. No 'not a handle' warnings needed for this unit. Here is a view of the front.
The sound was surprisingly musical. The treble control was a bit heavy handed; bass and loudness were a bit bloomy in quality but serviceable. All in all this would have been a sonic bargain in 1973 from one of the finest of the era's manufacturers. Mated with efficient speakers this would be the perfect foundation for a vintage dorm room system.
