Hey there. I finally finished my Whammy after getting distracted by other things for a while, but I'm at a loss as to where the power LED is supposed to go. It's not on the schematic and there's no obvious spot on the board for it, though there is clearly a spot in the case. I'm sure I could kludge something together but is there somewhere that it's supposed to go?
Thanks

Found this: whammy-review
In that review he talks about using a 20k resistor and wiring the power LED up to the C9 pads. Any issue doing that? The location certainly is convenient.
I just started a related topic regarding a blind-test comparison between the OPA2134PA and Burson Audio v6 Vivid, you might want to have a look:

On the most recent kits, the 220uF/50v according to the board and the schematics were replaced with 220uF/35v and 220uF/25v. Can anyone please chime in on whether I should order replacements at the correct value or if these are ok. If replacements are suggested, which brands are recommended.
