well, WHAMMY #2 for me is coming along. I replaced C3 and C4 with physically smaller caps, but still 220uf/25V just to get easier access to the opamp (for rolling). I also removed and jumped C1 and C5. DC offset when from 24mV to 1mV after remove the C1/C5 caps. Can I hear a difference? nope. maybe. probably not. But now that my DC offset is so low, I might try removing C26 & C27. Case is on order from Ali and will be here any week now I'm actually thinking of making a case like the Crack has. 4 walls of a box and an aluminum plate on top with the board mounted upside down on the plate. All the knobs, switches, jacks and inlets on the forward and rear part of the plate, and a knob it the middle to lift it up. Alternatively, if it's not too hot, I might put the Bifrost Multibit on top of it. So much fun.
