I went through all of the setup guide and everything checks out for the most part my question is in step 6 when you raise the output pot and it’s supposed to go to 9V or more… is there a too much on the more side? Mine rose to above 20v is this ok? The only other thing that seems off to me is that my meter runs a little hot. I can only adjust it down to roughly 6.5-7 db of gain reduction.

Now that I have passed audio through it there is a ringing when initially switched from bypass to in sounds kind of like
Feedback. Any thoughts on any of these things?  Thanks in advanced for your help!
