Default NAD 3020a PCB layout anyone ??


"David Harris"

My trusty old NAD 3020a has stopped working properly. Prob somewhere
between vol control and preout/in. Suspect J111 muting FETs.


** Suspect bad contacts on the pre / main links too.


I have a reasonable copy of the cct diag, but cud really use a PCB layout
to help me finally fix this.


** All you really need is a well trained nose for all the usual culprits
built into most cheaply made amps.

Cos NADs have every last damn one of them.


l probably replace all those old drying caps while Im at it.


** Make that a 100% certainty.

Got an ESR meter??

Be amazed how many small electros are totally stuffed.
