Kraken: Q2 transistor flip

[madbean]

Q2 was drawn incorrectly on the schematic (collector and emitter were swapped). The schematic on pg.2 has been corrected to show the correct orientation. You should flip Q2 180° on the PCB (on both the fabbed and single sided versions). I have confirmed the filter works the same either way and appears to sound the same. Thanks for the catch, Scruffie!
