Hello there! I exchanged some emails with the people from Keeley and learned that they switched from CA3080 to LM13700 in all of the Keeley 4 knob compressors.
I was wondering if it's possible to update the schematics we have here to match current production and make it faster to build them instead of a daughterboard every time.
Hi Travis. There's a few errors I'm afraid. I think you mixed up the inputs on the 13700.
Currently Clip 3 is grounded (and therefore all signal)
Clip 2 must also go direct to IC pin 4 (inverted input). Just move it down one row.
The 15K and 10n top legs need to go to pin 3 of IC.
2.2n top leg down one row
Try this ziotasgiorgos in the mean time until Travis updates the layout.
NOTE: After shifting the components around...make a cut at the green line.
Thanks a lot mate, but I think I'll wait till we have something final. I already have this inside an enclosure and if someone else sees something else, I don't see myself changing it for a third time :P
