great. glad you figured out your filter. i will mention on my site to use better quality integrator caps. yep the s/h is still available although im working on a revision.

I don't think a build guide is necessary but photos of these boards stuffed might be helpful, too. Thanks!!
so far the mineq doesnt have a bom because its the same circuit as the T.H. EQ and theres a bom for that. but there are a extras and a couple different things so i will put one together soon. mainly smaller 1uf caps from jameco(part no. 94161) and you need a 10mm spacer along with two m3 5mm long screws, i use nylon flat heads from mcmastercarr.
but to answer your question erthenvar sells the b100k song huei trim pots. but thonk or the manufacturer are the only places to get the b500k pot. i mention on my website, but you can order the b500k from me or also if you can deal with the smaller shaft trims with no indicator tayda sells the alpha version of the b500k.
multi turns would work fine, but as someone else mentioned the trim to "zero" is a really small turn on a normal trim towards negative volts. although if you are looking to trim all your vcas to the exact same dB a multiturn would be what you want.
heres a pic of an early prototype, so this one doesnt have a smd trim on the back. the chip is on the other side between in 3 and the sum out. also the 10uf power filtering caps on the back arent the right size. i assume your wondering how i made my "shitmix" in such a small package.
and speaking of the minimix. sorry for the confusion about the smd pads, as you can see in the pic you solder through hole parts to the smd pads for the chip and power filtering, although you would probably wanna make the 0.1ufs legs shorter. like in the pic a standard 10uf package would fit but i use these from jameco as they are 4x5mm, part no. 94212. i have some mouser carts floating around but they are for older modules. i have most of my important mouser #s on my site. in the bom it also tells you where to buy the parts, but i think you know that.
i guess i havent announced the mineq over here, so here it is...
The Żłob Modular Mineq is a simple 3 band equalizer which boosts or cuts the low, mid, or high frequencies of your audio source. It passes sound relatively un-altered with each band set at noon. This is not a filter, and full cut settings of all bands will not fully eliminate your source.This EQ is AC coupled so it’s best for audio although it’s possible to eq cv with some interesting results. The Mineq is a 2hp version of the Żłob T.H. EQ.
also on a side note, i have a couple new modules coming out that have been mentioned. i have a illuminated push button version for the dual vca at the fab and miniswitch, a dual passive 2hp attenuator with toggle switches should be out soon depending on how the new prototypes work.
and im about to pull the trigger on a run of alluminum panels for 2 other modules. im getting the minimix and the VnIcursal vca made in red on black. so look out for those in a month or so...
