Have anyone heard of this one? This is a a super rare distortion unit with clean blend and octave up. There is no sound demos online but the lucky few ones that have played one says it is quite a wild sounding circuit.
Schematic is a avaiable at Deadend Fx.
Hi.
ReplyDeleteAll four ICs in the stripboard are marked as IC1.
Thanks. Fixed.
DeleteCan I use a LED and a LDR instead of a nsl-32sr3?
ReplyDeleteI think you can do that. Just check the optocoupler datasheet so you can choose suitable LDRs and LED colour.
DeleteThanks, I'll try it. :-)
DeleteLooks like the original was working off 16-18V AC, have you had a chance to test your setup with the LTC1144 voltage inverter?
ReplyDeleteI know DEFX originally tried to redesign the power section to run off +9VDC using an LT1054 (probs in a combined charge pump/inverter configuration). It sounds like they couldn't get it working, possibly due to a high current draw: https://www.facebook.com/deadendefx/posts/2750599885219813
Going to have to order vactrols for this one. On/Off resistance is 150ohms to 25MegOhms. No heat shrinking LED/LDRs this time!
ReplyDeleteWhen I built my shoot the moon I just blacked out the back of the LED bezels.. as far as I can tell that's the only light source inside the box once the back is on and the jacks are in
DeleteHey Anders - built this one up today, and I'm getting very low output, as well as the whine that goes up in pitch. The LTC1144 is heating up quite a bit, too. I'm thinking that the power supply you designed for this may not be doing the trick. I got the schematic from DeadEnd and I'm going to try to work up a stripped down layout with +15 and -15 power rails, and then I'm just going to build a bipolar voltage daughterboard. Cause I really want to hear this thing now!
ReplyDeleteCool! Let us know how it turns out!
