Cambridge audio topaz am5

[Hjysks]

I bought Cambridge audio topaz AM5
Power button Light blowed i checked there voltage it shows dc 70v.
It was a small led for power up light why is that much voltage there??? Amplifier works fine but small sound balance only works right side when I increase volume sound comes back to normal both sides what causes this ????

Hello and welcome!
No idea about the led voltage, but the volume and balance pots may need some cleaning or replacement. Sometimes even rotating them up and down repeatedly may help to clean them.
