It was not the OT, I had it right the first time.

The problem was due to the totally different layout I created. This amp had to look different as it is for my daughter and her budding guitar interest. Due to the re-arrangement and my inexperience in routing wire for low noise, it was inductive in nature. The 2nd triode…[Read more]

I never really considered modding my BJr, but why not?

For the two stroke I placed the OT where it is for aesthetic balance, I think that moving it away from the input jack makes good sense, thanks for that as well.
