Does the Crack chassis have to be modified to accommodate the GP.

I would be interested to know if it will fit as well. It looks like the mounting hole for the GP is around 10mm and the mounting hole on the chassis is 8mm, can someone confirm this?

It looks like there's enough room in the chassis.  The hole in the Crack chassis is just shy of 9mm, and you can get a large round file to enlarge it slightly.  Due to the anti-rotation slot attached to the hole, drill bits may want to snag if you use them.

I have  One of the blue and white switch based pots with Dale resistors.  And it works fine sounds good.  I got it when it first came on the scene  I don't know if the switch has changed over the years but I do crank it through it range a few times every now and again to keep the contacts clean...John

I installed the goldpoint attenuator a week ago and I think it sounds fantastic. However, I am getting some popping sounds when I raise it up or down. I read that this is fairly common in stepped attenuators, but is there a way to get rid of this noise? Arn from Goldpoint said to try adding coupling caps, what kind do I need, and how do I install it?

A Valab or a Khozmo attenuator won't pop.  Goldpoint attenuators have been used for decades in our Foreplay preamp without popping (which has the same first gain stage tied to the attenuator that the Crack does).  Perhaps just try a Valab instead?
