Keeley 4 Knob update

[ziotasgiorgos]

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.

We can't live in the past now... can we.. :)

Regards n respect for your efforts.

Anyone?

[Travis]

I can do this if someone else doesn't get around to it first. I already did the Janglebox and Dynacomp. The Keeley is gonna come out a little bigger than those

[ziotasgiorgos]

Please do it. I need to build 2 of those and i can't stand the damn daughterboard!

I'd like to second the request. Love to build one of those as well. But I struggle to do the vero layouts. Don't know how you guys keep all those feeds in line .

[ziotasgiorgos]

Can anyone please help out? Pretty please?

[Travis]

I started working on this but gotta go to sleep! I'll have it up this weekend.

[ziotasgiorgos]

Thanks a million

Unverified

Had some trouble in the family... Didn't get the chance to thank you. I'll test this today!

[Travis]

Sorry to hear that  good luck with the build

Hey Travis, thanks for redoing this layout. I'll take a crack at it. Might take a fews days to get together. But I'm excited to test it out.

[ziotasgiorgos]

I finished building it. Doesn't work. No sound at all. I din't think i made a mistake. I build this really slowly

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.

EDIT: forgot to move 2.2n

[ziotasgiorgos]

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

Travis! SOS!

[Travis]

Oops. Got it right with the Janglebox but I got all dyslexic adapting Mark's Keeley layout. Sorry folks! Will change the layout when I get back to my laptop

[Travis]

ok thanks for spotting those errors Ciaran I updated the original post

Hey travis, you can tag it! Sounds great (and very low noise)

[Travis]

Thanks for verifying Battery Acid and of course thanks again to Ciaran for those eagle eyes.

Well, we do use vacuum tubes in our amps, 100ft unbalanced cable runs, BBDs, and the oldest transistors we can find...   ;)
