I have 3 of those well regarded Panasonic pots: 10K, 50K and 100k, logarythmic.
10k and 50K are not used and I'm asking $30/ ea.
100K has been removed from an amp and the shaft is slightly trimmed (a bit shorter than normally); I'm asking $20 for this one.
Shipping is $6 (any location).

Probably 50K.
Optimally, I would prefer 25K, but this pot is not available in that value.
With Brian's kit you already have 22k resistor shunting to ground. What I like to do is add another 22k Caddock in parallel with IN/OUT resistance of the pot. This cleans up the sound of the pot a bit, provides better tracking and lowers the series resistance.
I tried this method with another pot and it works great.
BTW, the 50k pot has very good matching between channels.

As I know, input impedance of GC is app. 20 k Ohm, so for correct volume curve must be used pot with lower resistance, max. 5 k Ohm, not 50 K Ohm. Also thermal noise of this value is bigger. 😉
So either GC is a special amp, or the pots I'm using are special, as 50k works perfectly well.
Why don't you try one?😉

If you use 5k pot with 20k ohm input on the amp, the amp doesn't have 20k ohm input resistance anymore, isn't it? I prefer to keep it closer to 20k ohm though, as my DAC has pretty high output resistance.
I'm using for connection between machines ultralow impedance ( 50 Ohm ) and my preamps give full output to this load, 'cos it is the best solution ( hum, noise, RF immunity and ( ! ) best sound ). Try it and you will give me thruth, I mean it quite seriously 😉 . In this case is not value of pot interesting.
Hi Peter,
What camera did you use to take the pic of the pot ?
( manual focus?)
Its really sharp and clean.
Thanks.
Ashok.

I used Olympus C4040 digicam (4 Meg) in auto focus mode.
The sharpness is usualy improved by using correct light.

All of Peter's photos are a pleasure to look at.
My digicam is crap (old sub 1Mp), I wish I could post pics I take with my Zenit...or my Lomo (most fun you can have with an automat).

I use macro on my camera works even better : O ) nice tight Pictures and REALLY CLEAR!! want a demo ?
Are this Panasonic type in generall still available? Or is it out of production?
Unfortunately I haven't the order code resp. model No from Panasonic.
