Here\'s another of my completed restorations. Produced from \'71-\'73 this Sansui has the rich, warm sound of the early capacitor coupled output amplifier designs. 25 watts/channel.
The black and silver theme with real wood veneer case is a classy combination.

What\'s been done?

-All the old electrolytic capacitors were replaced with new top quality selections from Nichicon, Wima and Elna depending on location and function (electrolytics have a limited lifespan and start to deteriorate after about 30 years affecting sound quality in varying ways)
-Fresh thermal compound was applied to the final output transistors
-Inspection of circuit boards/solder joints as work progressed, power supply voltages checked
-Amplifier adjustments were done with new Bourns trimmer resistors installed for stability and accuracy
-Transistors with known noise issues or high failure rates were replaced with new ON semiconductor equivalents
-Switches/controls thoroughly cleaned with Deoxit
-The unit was detail cleaned throughout
-The power lamp was replaced with a new bulbI will send the old parts if you want them, but only if you message me during checkout.Local buyers get a 30 day warranty and I can provide any future service needs.
