Now that is an impressive build!karatestu wrote: ↑Mon Mar 19, 2018 3:58 pm Been a bit busy. Have a look now
Added another psu for the front end. EI transformers and some more Avondale cap banks. All wired in with the tinned 2mm solid copper wire. I knew the psu was good to go as it was in use a couple of weeks ago. The relevant wire link was cut and the ends bent apart to separate front & back ends.
Turned it on with the variac again. Nothing blew up, no magic smoke Just checked DC offset and I think this is good to plumb in to the system.
More later when I am playing music..............
Awesome Stu! Congratulations! What a power supply, this will be a big and heavy amp once it sits in a case!
Thanks for sharing your DIY NVA-based project with us. It is fantastic that Richard let you explore this!
Reminds me a bit on my First Watt M2 clone build (one 300 Va R-core transformer per channel, plus ps with 2x 60000 uf per channel). I was a happy man, when I had finished it and it played music without any smoke!
Your ps is definitely stunning. And apparently, it pays off from a musical perspective!
