I'm tired of having to pay outrageous prices through only certain suppliers for volume pots. I would like to find something cheaper that is "almost as good".
Any recommendations on something other than Alps or the other expensive brand (the name escapes me at the moment).
How about Bourns or Panasonic conductive plastic?

They have nice 50k or 100k Alps pots for 1.95 and motorized Alps for 5.95. Buy a lifetime supply at these prices. I'm not sure of the taper, possibly someone can enlighten us from the product numbers.

<a href="http://www.farnell.com/australia/">Farnell (Aust)</a> has the Alps RK27111220k 20k dual listed for Aust$50.93, about half that in US$.
Farnell Part Number 642-990

The Noble conductive plastic on Polystyrene base is US$27.00 at The Parts Connection.

A few years ago an English parts supplier was recommending the Sfernice PA11 Conductive Plastic pots, saying it made Bourns, Spectrols etc. sound like they were mumbling into their beards. The PA11 looks like a typical square modular type pot (Bourns 91 Series) and was made for mixing consoles and other audio applications.

Never found the PA11 in Australia so can't comfirm or deny the claims of others. If you do find and try one please report back as to the sound.

If you are thinking of the same English parts supplier as I am, the recommendation was for the Sfernice P11, not the PA11, i.e. the cermet track device as opposed to the plastic film.

I have used a P11 for several years and agree that it is a significant improvement over the cheaper plastic film pots I have tried. I have not however compared it against the likes of a Panasonic EWC PA, since I consider the price of these devices to be somewhat excessive.

Conductive plastic pots is very much OK in my experience.
If you can find a Bourns retailer ( I only use Bourns! )in your area, they should retail at appx. USD 8 each for singles, USD 13-15 for stereo.....At least that's what I pay here in Europe. Available both in lin and log, in the most usual values.

Thanks for all your comments. The Brigar prices sound too good to be true...I'd be buying 10 if I didn't have to bring them into Canada.
I'm probably looking for a major manufacturer that has a dealer here, it can be pricey getting stuff across our border. Digi-key has a great system, I don't know about others.
I may try a Bourns, and I really should try Panasonic, I work for them and probably owe some brand loyalty. Just wondering what people had tried.

Geoff your most likely right, I think remembered the Hype properly though?
Could it have been Russ Andress (RATA) that recomended them ?

Farnell list both P11 and PA11 as Vishay, the PA11 is only available in 10k log dual ganged for Aust$43.76
P11 lin dual are A$16.24 5k and 10k
P11 single Lin are A$10.01 100R, 500R, 1K, 5K, 10K, 50K, 100K, 500K, 1M
P11 single Log are A$11.89 1k, 5k, 10k, 50k

Now how do they compare with the expensive Panasonic/Alps/Noble/Cosmos Pots?
<hr width="95%" align=center>

You are right about the source (Russ Andrews) and nearly correct with the hype. The full text was as follows:

"After a great deal of comparative testing we have finally found a superb metal film (cermet) potentiometer; the Sfernice P11. Available in a good range of values, single or ganged for stereo, this pot is sweet and smooth in the treble, detailed in the mid-band and very tight and clean in the bass. It makes conductive plastic types like Alps, Bourns, Noble and Penny & Giles sound as if they are mumbling along to the music."

As far as value for money is concerned, last time I priced the P11 here in the UK, it was a little under twice the price of an Alps 'Blue Velvet' and half the price of a Panasonic EWC PA. The situation could have changed now with the weak Euro (the P11 should be more competitive) and with Vishay's takeover (is there any specialist resistor manufacturer that they haven't acquired?)

Default Panasonic EWC and EVJ

I can't find any mention of EWC pots on the Panasonic web site. Could somebody enlighten me as to where I might find info on them?
I can only see the EVJs, which might be what I want (cheap, pretty good?). Digi-Key has them. Anyone tried the EVJs?
