All electrolytic capacitors can be replaced. Some capacitors can be added to the power supply rail through the tuner,
to improve stability. The power transistor in the power supply can be heatsinked to improve reliability. Lamps can be
exchanged by leds. Exchange the back-up memory battery.
These series of audio components soon got legendary by their outstanding build quality and good sound.
