I finished up an Ibanez CS-505 Chorus layout (from the 808 series) last weekend and would like to have someone/anyone proof it for me using the schem (links to both below). It does run on 18V, and it's labeled on the parts layout.
I bypassed the switching portion so it can be wired for true bypass. I also added a trimpot near the output for a potential overall level adjuster; the vintage CS-505 I had about a year ago was the best chorus I've ever owned, but the volume boost it gave when on was a dealbreaker. I just couldn't ignore it.
I have all ideas the current production Maxon PAC-9 Pure Analog Chorus is the CS-505 with tone ('Bright') and level ('Pure') toggles, but at $281, that's a bit steep right now. Figured I'd give the 505 a spin on my own layout first.

Schem - the yellow highlighted areas are omitted from the layouts, the blue lines are just connections in the schem

green traces: 6V connection
orange highlights: ground
pink highlights: 12V connection
I shaded these areas on the schem too - helped me try and make sure everything connected correctly.

Several jumpers on this one, but a necessary evil. Any questions or errors let me know - if everything looks good, I'll do a blacktrace PDF in actual size.

Thanks,
Buck
