So I am gathering all my parts to start building my first CMoy. Instead of using a switch and a volume pot how hard would it be to use a volume pot that switches off when you turn it all the way down? Has anyone done this before who could make suggestions on which pots would be best for this.

lol.... Best-CMOY-Thread-Title-Ever!

Anyway, yep that isn't a problem at all. You just need a pot with a switch on it. The perenial suggestion is the ALPS RK097. I don't have the pin out on me but essentially the pot has an integrated switch that you just need to put someplace on your rails before the amp. (right as the DC enters from the wall is my suggestion) Simple as that!

Anyway, you can get it from tangent: http://tangentsoft.net/audio/shop/

You wouldn't happen to know the Digikey part number? I am ordering all my stuff from there so as to save on shipping.

And for when you are ready to wire it up:

Digikey doesn't carry the ALPS (or at least I've never seen it there).

In fact (IIRC) it doesn't carry any audio taper switched pots.

It does carry a few switched linear taper pots though... But as far as I know none of them are stereo... so you would have to use a seperate pot for each channel. Some folks don't mind that, but I can't stand it!

It seems like there is probably some way of rigging up a circuit to shut the amp off when maximum resistance is reached... But that could get complex.

My advice is just to order from tangent... At the prices he charges you can stand to lose a little in extra shipping. (Besides that IIRC his shipping is pretty insanely cheap)

do you frequent anandtech? your thread is reminiscent of YACT, YAGT .etc

I do not. I remembered YaBB (Yet another bulletin board) and thought it would be a clever play on words.

Not true. It carries those Panasonic pots that people seem to suggest whenever getting ALPS isn't practical or possible.

I'll have to second the buying from Tangent suggestion. He's got decent prices and is generally a nice guy to deal with. You can also use this chance to score a couple of 470uF Cerafines for cheap, you know, for "future use". (Sorry for your wallet!

)

They have on/off switch versions of the Panasonics? Now that's news to me! I've never seen them.

When wiring up my CMoy what guage should I be using?

You don't need anything very big. The only thing that you might want to consider is not going super thin on the wires carrying DC... Even for those you shouldn't need higher than 22 AWG and you can probably get away with a lot less.

For signal wires there are lots of options. Most anything will work. I use wire from bulk CAT-5 so around 28 AWG solid core.
