clock divider and vca info is on the 4th page, s/h info is on 7th page...
A couple disclaimers:
first off, if you're in europe thonk only sells jacks for these builds that have 4mm threads which isn't quite long enough for a 1/8" thick panel. wigglers have found ways around it further down in the thread. thonk must specially order 4mm thread length, because stock jacks are 4.5mm from qingpu. you can get the correct 4.5mm inline jacks from erthenvar.
second, the svf is a complicated/intermediate build i.e. its not for beginners. it requires a good iron tip, at least .020" core solder and a magnifying glass doesn't hurt for soldering the 2sa798 matched transistor pair
third, the svf uses caps with 2.5mm lead spacing and 4mm case length. so you need small caps in most instances.
First is a charismatic compact(4hp)state variable filter based on a thomas henry design.
$20 for pcbs+ panel
2sa798 matched transistor pair $3.50(needed for the filter)
second is a simple,4hp, 3 band equalizer with boost or cut of high, mid, and low bands based on another thomas henry design.
$10 pcb + panel
Third is a 4hp passive attenumixer. The 3 channels are normalled to a sum for cv and audio mixing or individual use as attenuators.
$10 pcb + panel

all the components are through hole and easily sourced from most any electronics supplier. The only rare(harder to solder) part is the 2sa798 matched transistor pair for the filter. id prefer you source your own transistors from ebay. they cost $2.99 each plus $2 shipping but they come on the slow boat from china....
