I received a very dusty NAD 3020 from someone. I heard from a person that Dixie is great for contacts and circuit boards and that the receiver would work great after applying it. I was pleased because I had the D5 solution. So, I thoroughly cleaned it compressed air. Then, I applied 2 coats of short bursts of Deoxit to the entire inside. Sometime later, I heard from someone else that I wasn't supposed to do that. How bad did I mess it up and if I did, what can I do to fix it. I have not plugged it in and turned it one yet. Thank you!
