    NAD 7020 repair: emitter resistors

    I had a NAD 7020 dropped on the bench and one of the outputs blew when I was adjusting the idle current with various fixed resistors. So I decided to follow some of the suggestions from other folks (including @leesonic) that have repaired these units and thought I would document it here for...

    Power Amp with Pre Amp...Speaker Selector Knob Bypassed?

    I have a NAD 7020 and a pair of JBL 110's that I thought could use more power so tied in a NAD C270 power amp (to the speaker A terminals on the C270). I used the 'variable in' on the C270 as there is an input level adjustment knob on the back and I wanted a little more play in my 7020 volume...

    NAD 7020 Power Switch Repair

    So I snagged a 7020 and it does have what I now see is a common problem with the power switch arcing as I turn it on. And as I have read, it does it for a little less than a minute or so before stopping. The sound of this unit is great. When I got it I was able to remove top and bottom covers...

    NAD 7020 needs help finding L channel distortion.

    NAD 7020 receiver inputs/switch/DAC question

    Hi all - I have some older audio equipment my dad gave me - a NAD 7020 receiver and ADS L520 speakers. I am trying to set them up with a CD player but also with my computer/TV. The receiver only has one set of RCA AUX input jacks so I am looking for some type of switch that has 2-3 inputs...

    NAD 7020 question

    Picked one up recently, worried it would be a bit underpowered but it sounds great to my ears. However, when I turn it on there is a burst of white noise for about 2-3 seconds like radio static, not electrolytic static, and then it goes away (just drops off), prolly after a protection circuit...
