I installed the mod board I got from Steve (Hangman) today. I don't recall seeing any pictures of the mod board installed online. I should have taken pictures.
I initially tried installing it on the component side but I left the leads too short and the board wouldn't bend back far enough to allow the MID pot to go back to its proper position. I removed the board and then installed it on the trace side of the control board - there is enough room between the control board and the main PCB that the mod board can reside without touching anything.
I was able to get the control board out without having to unscrew and move the main PCB.
I also replaced C101,102,103 and 104. I couldn't get 250pf silver mica as Steve suggested in the article linked in this thread's OP, but I used 250pf SMica 500v. I also replaced c105.
The amp sounds REALLY good. To me the overall tone is much more clear, open, tight. I'm very pleased with the results.
Thanks Steve!!
