Mccormack dna-1 protection problem

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!

Ok.
It is time for an update. I Writing this because this part is often missing in threads like this.

It has now been 3 weeks since i did the re-soldering of the board. And guess what...
It still works:-) 

I am very pleased with my Mccormack and i feel like i don’t need any upgrades. I did recap it yesterday just to keep it alive a little bit longer. 

That is great to hear.

-I should try to brush up on my soldering. I haven't held an iron since Junior High School, but I was pretty good when I did.

@evilhifi   Good for you.  Nice that you have the requisite skill set!  and you can always have your unit upgraded by SMc Audio if the desire grabs you.
Enjoy the music!
