Yeahhhhh, I was wondering if this was coming up soon. I ordered the PPCB board this week, but would love a larger/deluxe version once this is verified. AWESOME!
Why is there 3 dual op amps used when this circuit could have been made using just 2? Is there a difference in performance when only using one side of a dual op amp IC and isolating the other side of each unused channel? Does this technique cause more SAG in the audio path?
Could you please make a smaller version, that fits into a 1590b enclosure? Two opamps are unused, so one TL074 instead of three TL072 would work. And the voltage doubler could be omitted, as most power supplis can deliver higher voltages, if needed.
Seeing as how most of your post comments are requests for other layouts, have you at all considered learning how to draw these yourself? The software that Anders, Sebastian, and I use is a free download that doesn't take very long at all to learn your way around. Google "DIYLC" - and as as always, we are all here to help each other out along the way. Good luck!

ReplyDeleteI saw that and was so confused too. Why not just use both channels or sub singles instead? It seems like it's a waste of an op amp.
DeleteI like to trace the layout, and this seems ok.
ReplyDeleteI find weird, too, the unused half dual op-amp. And a bit about the two 22nF in parallel: why not just one 47nF?
R5 10K connects to pin 6 of IC1, not pin 7.

DeleteHoney, I've been building pedals and drawing my own layouts for twenty years. I just don't have the time anymore

Aww. You called me "Honey" - that's the nicest thing anyone has said to me all week.
DeleteI wasn't asking for help, folks. I just suggested a simplified version of a great pedal.
