Mccormack dna-1 protection problem

Hi and thanks.
I did email Stewe and got a death sentence on the board. It will cost 900$ For a replacement main board. It is the through-hole plating that is the problem with my board. But I will try to re-solder it and put a copper wire through the holes. 

As it is now, when i press on the board a little bit it will go in to protection mode.

@evilhifi  That sounds right.  I called Steve a few months ago to see what was current with DNA-1 upgrades.  The last mod to my amp was 18 years ago. He said any DNA-1 with a 15+ year old driver board, they would only work on if the work included replacing the driver board because the traces would be starting to crack and fail.

Sent them my amp, got the new driver board along with new inputs, outputs and wiring.  Fantastically sweet, open sound.  Worth every penny.

Good luck with your amp.

Heureka! I think i have fixed it(knock on wood).I have re-solder the whole board. On quite many of the solder joints the solder hade not gone through the board at all. I’m pretty sure the problem was the through-hole plating. That is why the board was so sensitive for pressing down on it

Now i have played on it for a few hours. I have pressed down on the board quite hard and taping on it. Much harder and more than before.This treatment would definitely triggered the protection before i re-soldered it.

One mishap in the repair. When i started up the amp the right channel did not play. It turned out to be a capacitor that hade shorted out. It took me about an hour to find the little one.

I will post an update in a week or two.

Nothing like being handy with a soldering iron...
You should still call SMcAudio. I am sure Pat or Steve could give you some good advice on what you should replace or modify to benefit sound reproduction. Since you are so handy, they might even ship a new driver board and related parts for minimal cost.

@evilhifi  BIG +1 for @gdnrbob  The guys at SMc would probably enjoy talking with someone who knows their way around a piece of gear.  They are good guys and would probably make a deal with you for you to install some upgrades.  Boy is the new driver board worth it!
