hello everything is fine? Sorry to ask here, do you still have the schematic of the 5 mesa boogie equalizer? https://dirtboxlayouts.blogspot.com/2019/11/mesa-boogie-5-band-gyrator-eq.html
Got this built, but there's something iffy going on around the IC. D9 and D10 are permanently lit and the volume knob is emitting a test tone. All the fets have normal voltages and the LED's stay on even when they're all pulled. Will have another look tomorrow with fresh eyes.
Definitely something with the IC. I think I know why it's happening as the schematic does look different in that area, but how it can be moved around is a bit beyond me. I'm probably seeing 10 things when 1 would fix it.
I just did a quick visual check and the layout looks great to me. I am sure you have done so, but do the double check on your links, cuts, and definitely make sure there is no continuity where there shouldn't be.
Thanks for taking a look Brazdj. I’m going to give it a couple of days and come back to it with fresh eyes. It’s amazing how often a break can bring fresh perspective.

DeletePin 5 of the IC I think.

DeleteI see a new cut has been added. Thanks Anders. Tag it!
ReplyDeleteOne of the best Voxy style circuits i've tried.
