Be careful with these types of pedals. I built a fender and a Marshall style and haven’t been able to buy another PCB since. Literally the best sound I have been able to get out of my rig. I know @vigilante398 posted some Kingsley schematics in a thread on here in the past just search Kingsley. Just waiting for something interesting to come along because I’m itching to build something.
I traced a Kingsley Harlot v2 a while back, those schematics (with a couple of component value errors) are floating around somewhere. I do remember seeing a FSB post with a schematic for the Page, but anyway here's a gutshot the googles gave me:
It's hard to see values from the pictures, but 10M isn't outside the realm of possibility for a grid leak resistor. 1M is certainly more common, but I've also seen vintage Ampegs that use 5.6M. The value isn't super critical and won't affect the sound.
I will say that the Harlot that I dissected did have a 1M grid leak resistor, so I find it strange that Kingsley would use different grid leak values on different models.
