All electrolytic capacitors can be replaced. Some capacitors can be added to the power supply rail of the tuner section,
to improve stability. The power transistor in the power supply can be heatsinked to improve reliability.
Lamps can beexchanged by leds. Exchange the power main cap for a 4700F
or exchange rectifier diodes too and take a 10.000F for optimal sound and 2x 25 Watts output capability.



Very good.

These Sansui audio components soon got legendary by their outstanding build quality and good sound.
