TDA1524 - im looking for pot:)

[Low Rider]

No, seriously
The 47k volume pot - is it linear or log? I've seen kits selling with both types so how 'bout it?

Here's the datasheet http://www.nxp.com/acrobat_download/...524A_CNV_2.pdf

The pots are linear.

I have built this tone/volume control about 3 years before and i have used linear pots.

p.s. in my opinion tda1524 hasn't good tone control and it isn't good for hi-fi projects(this is only my opinion).

p.s.2 sorry for my Enlgish...

Thanks.

I have one more question:

The linear/contour option, what it actually does?

The contour (2,2k res. taken out) seems to boost LF at low volume, if i'm reading the graphs right.

I would like to have freq. response flat, when bass&treble pots are in middle position, regardless of volume setting.

It's a little noisy is what i heard of it, altough when i have builded a preamp with it once, it actually sounded quite good IMHO

Could you recommand me another (in the same price category) preamp? If possible, i would like to avoid using baxandall style t.c. in favour of voltage controlled IC's.

You'll find plenty of that in SF (lol).

I'd just look on Mouser, NewarkInOne, and/or Digikey too.

Tell me if you find out where to get CUSTOM pots

Hm, i have THE POT, just not shure which sort to use :ROFL

[antonis_x]

first if you want tell me where you are going to use this preamp,to know round about what you're looking for.
i don't know a really good volume/tone control chip.but in my opinion if you want a good quality hi-fi preamp with tone control,built one with op-amps. a good and simple project is that: sound.westhost.com/project02.htm and project97 is with baxandall tone control...
i haven't built this one but i have built other projects from this site and it works very good.
it's going to be a little more expensive than this with tda1524 but i think is better.

i checked mouser and digi and couldnt find any pot. they dont even have a garden section!
is this some kind of joke?

ha ha ya right
