A few people made noised about wanting to see these so here they are.

These are all pretty large, high res files, so I've uploaded them to my dropbox account.

I've mad a list of all components that aren't viewable, some aren't marked or have been scratched off.

Great pictures, :applause: thanks for the uploads
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

Yeah, looks like he's linked to my dropbox.

All good, doesn't worry me. I've had a go at tracing the Tube Cake...no way in hell I'm attempting the P2, I'll leave it to those crazy Russians!

Yeah, the tube cake looks very do-able but I'm with ya on the P2! There is no way in hell I would even attempt that one either especially not knowing the values of a lot of those SMD jfets and other components... looks like they all use the same board..

Ha, just getting back into building pedals after a bit of a hiatus and one of the first thing I see coming back here is this old post.

The link JOK3RX gave are the same photos that I posted originally - the ones titles 00x.jpg are the AMT P2 and the DSC_xxx.jpg are the AMT Tube Cake.
