frequencycentral - you are a legend sir.

Just one question; it looks like these could be mounted sandwich style parallel to the front panel, but I don't see any holes for standoffs on the boards. Any easy way to do this?

The VCO PCB measures only 78mm x 98mm, so there is plenty of room to add 10mm to two sides should you wish, assuming, like me you are mounting onto a 21HP panel. I guess you'd then have to design your panel to include space for standoffs too. Not keen to do this myself.

i'll take 2 vcos and a RM gratis please! thanks.

I'd have to see the build docs to see if I can do it but... of course Im down for whatever you do mate!

2 vcos, a RM & panel please (have to see how hard it is first!)!

I shouldn't be doing this but put me down for 2 x PCB's. Thanks!

Maybe I am blind, but looking at his layout I didn't see that. Maybe it just isn't referenced on there? Any chance you could do a screen capture and just highlight the area where this action happens?

Sorry to be a broken record about this feature, I just think it adds a lot of value to the VCO and I am not understanding how to implement it.

Looks doable for my level!

Thanks mate - 2Xpcbs and panel please!

If im not wrong, its the empty pad just between the VCO Scale and VCO Freq trimmers. There is a 270k Resistor connected to it.

Ah, i see that, thanks. I guess I just don't know where the other two wires would connect...

Andy's layout shows two of the pads jumpered for permanent non-LFO operation. Remove the jumper and connect the three blue pads to an SPDT toggle. This cuts keyboard CV in to the VCO and references it to -ve via the 270K resistor. Alternatively, connect the lower blue pad to the normalised lug of the CV input socket - saves a switch.

2 x VCO's & RM for me ta Rick

I'll have a panel when I have more spare cash too.

How much do you think panel would cost ?

reggiechacha · Post by **reggiechacha** » Fri Aug 17, 2012 5:04 pm

2 pcb and 1 RM plus 1 panel for me please.
