abakuzam · Post by **abakuzam** » 25 Mar 2015, 18:20

Hello fellas, i've decided to make some contribution to this forum, and i made a layout for sabrotone's Mark IV emulator, it's NOT VERİFİED, i'm not an expert with drawing layouts. Let's make this layout work

All the schematic work and vero layout from sabrotone.com. I'm just trying to add something to his great job

Note: You need Sprint Layout 6 drawing program to view and edit it.

C16 is unnecessary - leave it out or just increase C25 to 560p

On your Sprint layout C22/500p is shorted... Should go to the other side of the trimpot.

C28 positive lead is connected to the negative lead of C26, - C26+ and C28+ should be connected

C25 İncreased to 560p, done and thanks for noticing it

İ think it's correct now, thanks for the information

Version 0.2 of the pcb and layout

Edit: İ put the wrong layout, now it's correct one.

I would have suggested some minor changes on pcb.

R1 (1Meg) on the input seems to be missing?

Peter

i did't put that on purpose, i don't need that "pull-down" resistor to eliminate pops, i use that resistor on my switch board

you can add it if you want
