I know,because Mr Google say me,but I can`t buy this manual ,because I can`t pay it from Bulgaria or because this site can`t ship for me in my country.I know more online shops with this manual but I can`t buy it from my country
Guys I want only any simple schematics or the parts list. I know that anyone can help me with this ,but may be for $.
If anyone have a heart of gold in the our board I know that can help me and can`t stop waiting this salvage post

Greetings from Norfolk

Is the PCB single sided, it appears so from the phot. If so, you could make a photo copy of the trackwork, and then draw in the components, then develope the circuit diagram from this.

I have done it a few times, and had near complete sucess.

Maybe planet10 can help you.
He has a lot of old stuff.
I wouldnt be surprised, if he had that version scheme.

Send him a message/mail or contact him via his website: http://www.t-linespeakers.org/

derguteton,thanks but I have the schematics for the original 3020 from Geoff Moss on paper.
Now I must mail to planet10 for any schematics ,because this is my last hope for this amplifier.

Guys.,...the problem is there are many NAD3020-versions:

3020
3020A
3020B
3020e
3020i

there are some differences between them, especially the phono stage (mm / mc), preamp .. impedance switch, mute switch mono switch or loudness switch..

I have found schematics of most of them .. .. but not for the 3020A ..

having just acquired a NAD3020A i would be highly interested in the NAD3020A(!) schematic


The NAD3020A features:

phono stage with MM/MC switch
loudness switch, mono switch (no ! mute switch)
no impedance switch
power indicator leds (1-5-10-20-35 Watt)


Who can help us?

Thanx to Apple incrasing storage space to a GB & the high demand for this, the NAD 3020 service manual now lives here

http://homepage.mac.com/planet10/man...viceManual.pdf

as mentioned there are quite a few versions of the 3020 -- this is the 1st one.

Also perhaps an aid is the 7020 manual

http://homepage.mac.com/planet10/man...ly_servMan.pdf

the only references to the insides of a 3020A i have is this picture (shrunk to fit here -- i can mail a larger one if it will be useful)
