Money: It’s 180 feet for $15, or about $0.08/foot.
Math: E=MC^2
E=MC^2
(right now, before saving, the money bit looks right in the preview, the math doesn’t).
(right now, after saving, Discourse ate the $ signs around the math formulas, but didn’t do any other fancy rendering. The money bit still looked right. Hmm.)
What potentiometers among the TT Electronics P09x Series on Mouser can match the usual of the bom?
What I’ve discovered among them is they have different types of shaft (smooth, d shaft with different orientation of the flat side and knurned), they have different shaft length and some are switched so they’re all a little different from others. It all makes it difficult to find the one that matches the usual “suspects” all of us will find work better.
does anyone have a good source for the vertical alpha pots on mainland europe?
i’m in need for lots of b100k and b10k pots, the only source i can find is musikding.de but they seem to only stock small quantities…
Yeah, it’s a real problem! someone here had them on aliexpress, I remember, but I can not find there. There is also uk-electronic with the alpha 9mm pots, but I could not find b100k… maybe also out of stock?
This is handy for selecting capacitors. For the best timing of the 3340 it looks like the right choice is polystyrene.
Polystyrene Film : … With temperature coefficients as low as 30-40ppm (special) and typically less than 120ppm (standard), they have excellent linearity of temperature coefficient … Dielectric Absorption (.02%) is the lowest found in any capacitor variety. This makes the polystyrene cap the first choice for all critical timing circuits, such as VCO …
Secret tip: I asked the people at musikding if they could reserve some pots for me, because they did also not have enough then and they kindly did. It took ~2 weeks but I got around 50 b100k then
