Interfax Harmonic Percolator stripboard layout 23rd October 2008
Based on the most recent, general consensus schematic (apparently the pedal 'evolved' during its initial production). It's a nice easy build, and you'll only have trouble sourcing the transistors. It sounds really good, and it actually does lift the harmonics out of the general fuzz/crunch. Sounds pretty accurate to my ears, but then I've never owned a real one. Can't get teh Albiniz as I've stashed my Electrical Guitar somewhere safe and I'm testing it into a Fender Deluxe Reverb.Harmonic Percolator stripboard/veroboard layout
Update...
Here we are. Finished in finest blue/brown gingham with a laquer coat for longevity. The switch disengages the diodes for loud/openness. I also noticed, whilst playing it properly for the first time last night, that there's a really nice kinda compressed clean sound when you roll the gain off. Also that there's probably not too much need for an extra boost circuit after the main one.
Demo!

Thanks!

re. the switch: when adding the diodes using this layout, solder them standing up and use a spdt switch to connect them to either ground or nowhere.
