Let me know how it works . 500 pf would be extreme bright.

Only works in Thin mode.

I recently added the PAB to the Tramp. Worked well. Later, I tried this mode with a 200pF cap as per Coco's schematic. The "Bright" cap worked well; I like it. However I note that the PAB has no effect at all. Switching in / out adds no boost at all. Is this something to be expected if adding the "Bright" cap?

Appreciate any feedback.

Coco, I recently added the PAB to my Tramp using a 1M pot; it works well, providing a nice added boost but as suggested, loss of tone stack.

Just not I tried the "Bright" cap mod, adding ~200pF cap as per the provided schematic and lay-out. I love the added brightness however I note that now the PAB is showing no effect whatsoever. Switched in or out, I can't detect any added boost at all. Is this something that might be expected with the addition of the "Bright" cap mod?

Appreciate any feedback and guidance.
