Saw a NAD 4020B tuner listed at a local garage sale so I thought it would match up well with my D3020 amplifier.
It is in good condition and it sounds very good but it is in need of a alignment. Any idea what is the best way to align this tuner?
I'd start with the service manual. Only the 4020A available at hifiengine. I try that first and see how close they are internally. The 4020B service manual is available at servicemanuals.net for $16.99.
