[sdiy] Potentiometers and Mounting PCB's

[David Ingebretsen]

These Panasonic pots are a bit pricey, but they are a solid mount to the PCB
and panel.

They are basically the ones John Blacet uses. I've found the mounting
geometry for the pins is close enough to the Spectrol or BTI pots (like MOTM
uses) that you could use them in the same holes if you want to.

For what it's worth, I found that with a small'ish PCB (like the CGS Steiner
filter), the pots you linked to work fine especially if you have several of
them on the edge mounting to the panel.

~~ with brackets did not have a threaded bush.
~~ 
~~ I've seen that a common method is to use a "stooge" bracket that goes
