You can use an inline socket such as this:

Yeah, I went with Brown because John is my hero 

I admire your dedication to making this work. It's one of the most challenging projects here!

F-N A' that's good news! I actually have one of the LT1054 which I wanted to test out. I'm considering it for a few different applications, including another analog delay design with higher voltages/current.

I'll add this info to the Road Rage docs since I'm going to expand on the info in there anyway,

Thanks a bunch, fellas!

Hmm...I must have mis-read the datasheet. I thought it said 8v on the Compander. 18v is much better, considering the application! In that case, NM----you did not damage the compander.

I would be really surprised if you killed the clock. It's rated at 12v, so frying it at 12.6v seems pretty unlikely. Maybe take it out and re-seat it?

Great work! It's good to see some pics of the AB. Not to many show up here.

The last few rolls of pre-bond I've bought from smallbear have actually not been pre-bond. The are tinned, but the strands are not bonded together like they used to be. I don't know if this is just bad luck on my part, but I've gotten three rolls like this. I don't like it so much this way as the bonding stiffens the wire up quite a bit, which I like.

This other stuff is also stranded, but I guess the thicker wire and teflon sheath make it a lot stiffer.

I picked this up after seeing a link somewhere. It's 22AWG pre-tinned 7-strand (not pre-bonded). I'm quite pleased with this stuff. It's a teflon coating and does not shrink under heat. It is also stiffer than the normal 24AWG pre-bond stuff I use from Smallbear. A little pricey, but at 250', it will last quite a while. Here's a pic of it with a comparison to the smallbear roll.

He has other colors, too.

Try replacing the compander first, if you have an extra. You should be able to use a NE570, if you have one.

I tried mine at 15v briefly, but got no delay. However, my chips were undamaged and worked again after running off 12v regulated.

Awesome!

Yep, you guys are absolutely right. C4 needs to be in there.

Sorry guys, I will fix the Zygote docs. I'll also address the lack of application info in the RR document too!

I'll have to check the datasheet to see if the layout is compatible for the RR.

That should not happen. This might explain the volume loss. Mine does not have a noticeable volume drop when engaged.

You need to find out why Vd is dropping! Vd supplies only the Clock and BBD. The compander and i/o stuff comes off the 9v rail.

Josh, if you don't have a 9v regulator, use a 2k2 resistor to get about the same result (if running at 12v).

Here's a pic of my set-up.

You can decrease R33 and R36 to 15-22k for some added output. This is the least likely place for it to impact the character of the pedal.
