NAD 3020 Switch On Power Thud Sound Issue Repair - Retfurb Retro Audio

In this video we have a NAD 3020 Stereo amplifier, Which has an issue when powering up the unit.
The system has a loud long thud / bang sound, As soon as the power is put through the device.
It is only when turning on the unit and does not happen when powering down.
The system does contain a muting circuit on power up, So hopefully this is all that needs repairing at......



The NAD 3020 line of amplifiers, Is widely regarded as one of the all time greats. It was a giant killer in the day and still holds its own today.
It is a great sounding amplifier and for the original retail price it is hard to beat.
