Hi Zen Mod, I don't know what size your FE boards were. The one Nelson laid out was 3.5"x5.5", which put it in the $65 with shipping for 10 pieces.
Hi Mike, I don't think I can change the gerbers from another package though I have never tried to import them (maybe I will have to look into that), I just use the schematic capture and PCB layout program to make new boards. On the new board I am making, it fits between the current long screws which are on a 2.75"x 4.25" pattern. I laid out the PCB to use the 220uf Silmics for C2 and C3. Also I like to use multiturn pots that can be had with the screw on the top or on the side, and you can reverse them, so they can face up or down, and I always try to put them near the edge of the board so easier to adjust, and if possible make a location on both edges so you populate whichever one you want up. I design stuff from the point of easier to service if I can. Too many times working on my car I wanted the Toyota engineers throat in my hands.
