Thanks Grainger, I did post to the decware support forum, the first new thread for that preamp in over a year, I am not hopeful. I did add a new component just last weekend, but the little pop was there before adding the new phono stage, it did it before with the old one too. I will just keep an eye on it. If the pop worsens I will take it down to the bench and investigate. I still have the documentation, emails, and schematic. It's been a very solid preamp.
as long as it sounds good, who cares?
