B6.8k through-hole potentiometer?

[cal3713]

Hi folks, does anyone know where I can get one of these front panel potentiometers?

I had a power supply shipped to me and it broke off a pair. I can find the b1k (voltage control) at mouser, but can't seem to locate a b6.8k (current control). All the ones I see are even values...

Thanks.

You just won't find an off the shelf 6.8k pot, nobody would buy it. Post the power supply schematic,
and maybe a 10k pot will do.

Damn. Unfortunately it's a lab supply, so I don't have any schematics...

Add a 21K or 22K resistor to a 10K pot make it to 6.8K

Thanks for the suggestion and math. Much appreciated.

Equipment makers order their pots to spec, not off the shelf. You won't find a 6.8k pot.

So flip a coin and/or try 5k or 10k which are readily available.

In principle, they "should" work, worst case some scale printed on front panel may give you somewhat higher or lower than printed value, no big deal.
