Use Paypal (friends&family!) for payment, email: firstname.lastname@example.org and send me your address. Build docs can be downloaded from here:https://www.dropbox.com/s/64tkrrld0f73xo7/JSI-PetersonPreamp-BUILD.pdf?dl=0Some IMPORTANT build notes:- Please build it following the order of the build guide pictures.- You need be able to drill and file the Hammond 1590BB enclosure. PCB can be used as a "drill guide".- Only the SPST (/SPDT) foot switch needs wiring. Pots are soldered LAST! and cut the component legs as short as possible under the pots.- BOM has part numbers for Mouser and Tayda Electronics. Some components have only one source and need to be bought from there. Vactrols need to be bought elsewhere, like: Thonk, Synthcube, Musikding, Banzaimusic, Tubesandmore, Ebay, etc.- You can build the pedal without the Delta DC-DC converter, but then you should use a quality +24VDC linear power supply.- Pay attention to the polarity of your power supply. Header J5 can be used to switch between "center positive / negative". The most of the guitar pedal power supplies are center negative. The most of the regular DC power adaptors are center positive.- Current draw is around 25mA (+24VDC). You can test the unit even with a 9V battery (use clip connector), but the battery probably will not last many hours.- Have fun building!
