Deoxit Gold...Not Just For Tubes?

It's clearly not just for tubes and says so on the literature that comes with it. I use it a couple of times a year, but to tell the truth, I really dislike the sound of the system right after I use it. I just do it for maintenance purposes.

That's why I mentioned the old tubes with steel pins cleaned to "gleaming". A couple of the tubes I've gotten like that were absolutely shrill and unlistenable - very out of character from what I had come to expect of an RCA. One set was RCA 12AY7 black plates, another was RCA 12AX7 gray plates. 

Helps with PC connections.

Thanks for the feedback! I will start applying and see where it takes me.
