1157 Mini ADSR Bill of Materials (Tayda Edition . . . lol)

All parts can be sourced from Tayda with the exception of SW2 - (ON)-off-ON Toggle Switch for the ADSR Trigger.
These can be easily found on Ebay.

Tayda is almost always out of B10k 9mm Potentiometers, so I also included a link to Modular Addict.

I had to get new knobs as the ones I intended to use were a bit too big and did not fit… I had not realised how tricky it can be to get knobs!

6.4mm shaft ones for the Alpha pots seem less common…

Ordered these in the end.

Fifty of 'em? That’s a big commitment to yellow!

I have lots of 1900H clone knobs on my Eurorack (well, not fifty. Lots compared to any other knobs though.) It’s rare you can get away with anything bigger in Eurorack, that’s what bugs me about that format.

Definitely gotta watch the shaft sizes, 6 mm knobs for 6.35 mm shafts is a problem. Alpha does make 6 mm shaft pots though.

6.35 mm knobs for 6 mm shafts is a solvable problem.

https://www.thonk.co.uk/product-category/potentiometer/ Thonk is usually a good place to get potentiometers , but they are temporally closed . :frowning_face:

I mainly posted these as a “USA Edition” BOM since Sam already has the the links for the Components from UK Suppliers.

I have posted a couple other US BOM’s as well :slight_smile:

Happy Building!

the 20ks still seem to have vanished from every where but china
and those take 2 to 3 months to show up here in the states for me .

Amplified Parts shows 25k in stock:

Not sure what you need 20k for (the ADSR uses 10k). If they’re voltage dividers, using 25k (or even 50k) should be fine.

they were for something else . just commenting on how they [ 20k pcb mount ] seem to be scarce at the usual suppliers

Had to order another 50!

I am actually building the 1158 module. I got confused because it says 1157 on the BOM for the 1158. If there is a Tayda/Mouser/ etc… version for the 1158. I would greatly appreciate it!

Thanks!
