I'm putting the finishing touches on the NAD 3020 Series 20 vintage amplifier I've been working on. // Kindly sponsored by PCBWay - https://www.pcbway.com/
I added proper screw post/banana plug speaker terminals and am trying my luck with adjusting the idle current and DC offset.
The method I used for the idle current is laid out here (post number 7): https://audiokarma.org/forums/index.php?threads/nad-3020-work-including-idle-current-adjustment.860328/
