Re: Pots in parts lists

2005-05-30 by Richard Brewster

Since pots are variable anyway, the value can often be substituted with
little impact on the circuit. You can often substitute a 47K or 50K pot
for a 100K pot and vice versa. I expect that in most CGS modules a 47K
pot will work where a 100K is shown, and in most Blacet modules a 100K
pot can be substituted for a 50K. Same for 470K and 1M pots. For a 22K
you could try 10K or 47K.

You could probably build all of your modules using 10K, 100K, and 1M
pots, 90% of them being 100K. Dual-gang pots are special, of course.
Center detent is a nicety, like the one on the Blacet Time Machine,
which I didn't bother with. Unless there is a trimpot that let's you
tune that detent to a precise setting, it's not worth a whole lot.

In almost all cases you can use linear taper pots. Only a few special
mixing applications need audio taper.
