ok so nearly time to start re assembling.Hopefully have it up and working this weekend, although the amp did have a small fault, and hopefully it wont take alot to get that sorted out👍
sounds like a plan.
Cheers for that. It certainly has. Has become a labour of love this, way beyond what I originally anticipated but I'm looking forward now to seeing it finished. I was going to start assembling, but I recon it's time for ☕ and tv

Looks great. The objective with my one though is to improve an original machine. Not sure I like the blue LEDs though. Prob looks realy good with the different front cover though, if a little bright

So I've finished the modified heatsink. Though of and tried a few approaches and went for the simple realy, at least this time around. It's simply removed if required. Just waiting for the etch primer now then I'll give it a very lights spray of gold paint

The original isn't fantastic and in today's increasing average summer average temps it can only help 👍
Ok, it can only help, and you've got plenty of room back there, but sure it won't touch any components? I have a question, sorry if you've already discussed it and I haven't seen it. Someone uploaded a YT video, the NAD 3020 with blue Led's. ( I agree that they are very bright ) And I see a huge relay there, which points to the addition of a protection circuit on the output. Do you plan to incorporate such a circuit? Really, I always suffer when my 3020 turns on, before repairing the PWS the noise and movement of the speakers was to be scared..... I think that here at DiyAudio they have already done it, but I would like to install something designed specifically for the 3020.
I don't realy get that with any of the ones I've repaired, a slight thump realy. You could install the muting circuit as in the B version, but enen the B had a weird buzz that sometimes be eliminated by removing and shorting the 2 FETS and upgrading the Caps C533, 532,53110 100v,but not sure how easy it would be to do the muting, ive not tried that yet. The A version is very simlar with a few tweeks but the B is different in many ways.Someone like mooly would def know, but i wouldnt think it would be an easy conversion.
my next version of the series 20 will be to incorporated the mm/mc phono circuit
