cw / ccw viewpoint for pots on cgs75?

[mcetilia]

hi all,
i'm just finishing up my first two cgs panels, both cgs75s (the VCSs),
and wanted to make sure that i was thinking of counter-clockwise &
clockwise correctly before wiring up the pots…

i'm thinking you'd be looking at the pot from above with the pins facing down?

cheers,
mark

not sure how i missed this before:
"The pots are viewed from the rear"

so that's 1/2 of the equation,
the other half being whether the pins are pointing up or down
when looking at them from the rear.

i guess i've got a 50/50 chance, so i can just try it out & see…
then if the polarity is wrong, just switch them around.

but if anyone knows offhand, it would be nice to just plug & go

cheers,
mark

Hi Mark
to e-m

Usually Ken's wiring diagrams show the pots from the rear with pins pointing upwards.
This is from Ken's VCA page:


Viewing pots this way the ground connection will go on the left, input or +V on the right. The main point is to get the centre pin connection correct, the other two just determine which way the pot will operate.

Physically take a pot, and twist it CCW. Look in the opening near the pins and you can see the wiper (16mm alpha type pot). That is the CCW end.

thanks andrew, ken…
it all makes sense now.
the modules sound amazing btw,
can't wait to get these racked up
& start on the next round of boards…

cheers,
