Hello - can anyone explain which size LED's I should get to fit into the 3mm LED Lens I got. The BOM has 5mm LEDs, I had some of these at my space and they don't seem to fit. Should they, like, click in?

Thanks!

The holes are sized for 3mm LEDs in holders. (Lens maybe as well.)

Great! T-1. Yeah that is the trick. I was searching 3mm and getting nothing...

Thanks everybody. Slow me keeping this thread alive!

So I finally finished the mini synth and it sounds great.. My one issue is with the vcas. When I plug my vco into into either of my vcas I get a bit of bleed through. I made sure the vca was outputting 0 dc and minimized cv bleed w the trims. I also gave every module it's own plug to the power supply so I'm stumped over this.. Any ideas would be great

Hmm I guess I didn't match the 548s as close as the dual. I also don't recall having bleed on my test power supply. Feels like trannies or my mono rocket case are to blame.
Besides that, this thing is amazing. I gotta thank everyone here for posting their experiences/troubles w the build...It helped me a lot.

Question about the DUSG wiring. Is the VC IN pot just an attenuator. Can i put cv input to signal in of the pot and then out to F on the pcb? I thought could, but iam somewhat confused after lookin at the schematics and wiring documentation. hmmm.....

Another thing i notice that there are three different M marked inputs on the board. I'm assuming the trig out is on the two M's near the 5V6 diodes. What's that third M input for?

Cheers, Heikki

So can anyone tell if i can put the VC input as an passive attenuator? CV In > VC In pot > F on the pcb?

Cheers, Heikki

Heikki, if I read the schematics of the DUSG right this wouldn't work as intended, as the CV In at the same time feeds the negative input of an op amp through a 470K resistor - the attenuator is designed to be a polarised attenuator - wiring it your way this wouldn't work I guess hmmm.....

Ok, i thought so too, but had to make sure before rewiring cry

Thanks

Rico,

Can you tell us the list of modules in your case??
Thanks

EDIT;I saw the list in the "gloat thread" Guinness ftw!

EDIT: I think i have wrong kind of power supply in my uzeus no ground eek!

Ok got the quadslope all wired up now. It is working apart from one dead led.

There is one issue. The voltage it outputs is wobbly and shaky is it somekind of grounding issue?

I did put all the pot & jack grounds to onky one of the boards. Could that cause issues?

Please help

Mouser seem to be out of 20k or 25k 9mm small 9mm pots...

http://uk.mouser.com/Search/Refine.aspx?Keyword=311-1902F

anyone know of a suitable alternative?

Try Small Bear, I know he's out of the 50k Linear but I think he's got the rest in stock. (Incl. 25k.) If Banzai Music is easier for you since they're on your side of the Atlantic, they should have them as well.
