Ampeg tone stack modification
#28
Thanks for posting your thoughts! I do plan on taking some pictures and posting the simplified install once I get the conformal coating. Which might also allow the module to fit between the pot and circuit board as the old one did with only a small amount of manipulation.

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!!

I did send a few out to people that were very interested and didn't care about the module being coated or not. If you are interested in one just private message me.
I am working on a "store" on this site where you can buy the kit, but I am dividing my time between a lot of projects, So if you are ready to install, Just message me and we can go from there.

Steve,

How do we go about ordering some of these? I didn't know they were ready to ship out!
