I just built up an Aion Azure PCB and it sounds awesome. Going to have to give this one a shot soon! Also - if I'm not mistaken, you can add a rate LED by attaching a 22k resistor to the strip that has the 4k7 resistor and the anode of D2. Resistor to + of a super-bright LED, then - to ground, and the LED will follow the chorus rate. Untested on this layout but I plan on doing it as soon as I build this!
Hey Ian - I'm sorry I am just now seeing this comment, blogger plays horribly with my phone and I only get full access to comments when I use my laptop. I have since boxed up the Chorus build I did to verify this layout. But I am going to build another quite soon, and if you still haven't gotten yours working by then, I will happily post my IC voltages once I measure them. Also - just a troubleshooting question: where did you get your BBD and clock? I've been getting the Xvive reissues from Cabintech here in the USA and have not had any problems with counterfeits.
I cannot get this or the Julia build working. WTFudge? It's driving me bonkers. I've tried multiple 3207's and clocks from different sellers, and it refuses to operate correctly. I'm using a 9.1V zener but not the specified 1n4739a. Could that be the issue?
This circuit really sounds beautiful. I think it's just a hair darker/quieter due to the omission of the Boss buffer. That may be the difference that we're hearing. The Ce-2 was originally made with the 3007 chip which could be a little more extreme. But, in my experience are noisier too.
This is a must build, plenty rainy days in UK!!!
ReplyDeleteI see Banzai Music (banzaimusic.com) have the IC's for a decent price. Cant't find any other sellers, apart from the usual rubbish on eBay.

ReplyDeleteTag it, snube. This layout is golden!!!! VERIFIED.
ReplyDeleteNO WAY! Thanks a lot, man. TAGGED!
DeleteChris, I don't suppose you could post your IC voltages. Can't get mine going. Cheers

DeleteNo worries Chris, its all working - just a dodgy transistor
DeleteIs it fit with 1590bb?
DeleteYes, just think about where to put the 9v socket and jacks. You need to leave as much space as you possibly can

ReplyDeleteFound the mistake. [eye roll] Sounds great. Thanks for the layout. Thanks for the link O.T..
DeleteHey Tom, for the CE-2 try using slightly higher gain transistors (around the 450-500hfe mark). This should get it going
ReplyDeleteIt's going, I just misplaced a ceramic lead. Good tip though. It sounds, good but not quite as intense as my 80's MIJ.
DeleteMine wasn't as intense as I expected too, could be a transistor thing. May have a play with different hfe / transistor values
