Can anyone help please ?
I need a service manual for a Nad 4020 tuner - I need to re install the string which operates the tuning function - Looks very complicated but with a picture I might get there....
Thanks in advance.
Thanks for the diagram, however, this is quite different to the layout of my 4020 - My 4020 is the B version (last production version) and I'm wondering if NAD altered things slightly ?
I am new owner of NAD3020 and 4020B tuner.
As you probably have seen I "repaired" 3020 ;-)
Today I powered on 4020B and... no stereo effect, but beautiful analog sound.
I have got the schematics of A version but the resolution is filthy, could you upload the schematic for B version or advice where should I look for fix stereo decoder?
Thank you in advance!
PS. the inside of the tuner was sealed - no dust inside, the parts look like the are straight from the factory, even smells like new.
the problem solved,
just weak connection in antenna plugin, too weak signal to switch on stereo signal.
I am lucky with this last NAD purchase...
anyway the schematic in good resolution is still wanted...
