The first one is for a vintage version (schematic available here).
The DIP version of 1496 had a different pinout.
The second one is for the modern vesion and it could potentially fit in a 125B size box (there is no schematic but a PCB layout here).
Not sure if they have been verified.
You should be able to use Mark's Bipolar Voltage Converter.
Have a great new year!
ReplyDeleteHappy new year!!!

ReplyDeleteHappy new year! Sweet! I was just looking for a ring mod to build.

ReplyDeleteHappy New Year!
ReplyDeleteHappy new year! What a great addition -- ring mods are one of my favourite effects. Tis one's a bit of a scary size for me just now (and thanks to this site I have a huge build list already) but I'll definitely be tackling it at some point in 2017.
ReplyDeleteHi
ReplyDeleteIs anybody ging to Build this one? I started a board Of the modern version But i cant find a 10uf ceramic cap. If i Use a electrolyt what Would be the right Direction?
That's a bipolar electrolytic cap.
DeleteIf you use a polarized cap I think the + side should connect to Blend 1.
What type of i.c. is the 8038? I can't find anything with that code number at my suppliers.
ReplyDeleteIts an ICL8038. Should find on Evilbay for a couple of quid/dollars.
DeleteI recently bought 2 on eBay for like 3 euros with Free shipping from ebay. On eBay you'll find a lot of cheapo function generator kits with this chip.
DeleteAnyone have a good source for an ad63? It seems like they are discontinued and cost around 7 or 8 euros
DeleteCall it verified! Built the modern version. Sounds very similar to the YT vid i'm surprised to say. Getting some lovely sounds out of this. Great job Alex as always.
ReplyDeleteBrent, i think i got my AD633's from Banzai, but i don't remember paying what there charging now.
I should have added that the Blend pot is working backwards so 3 and 1 should be swapped.
DeleteThanks Gavin!
DeleteI've swapped the Blend's lugs.
How are you powering it? Did you use the bipolar charge pump?
DeleteYes, i'm using Mark's Bipolar Voltage Converter.
ReplyDeleteGreat! One more question, is your AD633 labeled with ANZ or JNZ? Seems there are a few versions out there, and not all are quite the same.
DeleteRead the data sheep closer. ANZ and JNZ have same pinout. But there are also JRZ and ARZ, that have a different pinout. Not sure which one this layout is for.
Deletedatasheet: http://www.mouser.com/ds/2/609/AD633-877235.pdf
Keep on reading it closer.
DeleteNote that the ones with different pinouts are in SOIC (SMD) package and PDIP (through hole). So the SMD chip is not pin-to-pin compatible with this layout.
+m
Ah, I see that now. My bad. Thanks.
DeleteMy AD633 has JN after but no Z
DeleteHey! Just wondering what way the 2u2 caps are supposed to go in case you're using bp electrolytics. Anyone?
ReplyDeleteHi there guys, the 4558 is something specific or can I use any opamp (NJM, TS, JRC)?
ReplyDeletefor a non polarized cap, take two electros of double the value, and tie the cathodes together (-'s)
ReplyDeleteafter that you can use either anode either way, and you'll get a no polarized cap at the value you need.
hey, anyone got the pinout for the old can style chips?
ReplyDeletei got some ua796 chips, but i can't find the pinout for them to save my life. appreciate thehelp!
peace!
PjP
awe, fuck, i don't think these things are gonna be compatible, what i have is 10 pin chips in a TO-5 package. FML!

ReplyDeleteAnyone have any luck with the vintage version of this? I managed to get it mostly working by adjusting the pinout of the 4096 to take signal from pin 2 (as in the original schematic), but I'm getting significant carrier wave bleed through the whole thing, even once the input trimmer is perfectly biased. I've tried to adjust the voltages at both the carrier and signal input and I've swapped out 4096s. Any suggestions for getting the 4096 properly balanced?
ReplyDeleteSorry, I meant taking the sine wage signal from pin 2 of the 8038 (the layout has it coming out of pin 1).
Delete@TTonn
DeleteAny thoughts on modding this with a Hi/Lo range switch for the oscillator, similar to the Fairfield Randy's Revenge to get some trem/vibe sounds out of a lower oscillator range?
