Knobs and one more thing ....

[orson whitfield]

First off this is a request. I would like to know the best places to get knobs for our DIY at resonable prices with a good selection. Also, where small quantities may be ordered. Secondly, This question poped into my mind but it doesn't deserve it's own thread so i am putting it here: What is the model and microphone manufacturer with the largest diaphram diameter/area? Why are many diaphrams I see "so" small in surface area. Is there a direct correlation between the size of a diaphram and the quality of the sound? I say "so" because perhaps they really aren't.

I tend to think that Digikey, Allied, Newark, etc all have fairly good selections of knobs. And I don't think the prices are bad. And you don't have to buy huge quantities.

6$ a knob at digikey, mouser and newark isn't bad? that would mean i have to spend 260$ just on knobs alone for all my projects. the knobs for my GSSLs would then make up 30% of the total price for the box!

Pearl mics have pretty large membranes. Old skool carbon mics sometimes had large ones as well. I've used 15" loudspeakers as microphones, does that count? :razz:

Here is one place:http://www.allelectronics.com/cgi-bin/category.cgi?category=310&type=store They aren't too bad.

Another:http://sales.goldmine-elec.com/prodlist.asp?catid=2122 Their inventory shifts from time to time.

If you want machined aluminium knobs, then you're gong to pay more. But Mouser, for excample, has lots of knobs for $1 and under, and more in the $2-$3 area too.

The other places, I'll admit are more. I should have looked through the catalogs before posting.

Plus I was thinking about people like me who only do one project at a time. Can't imagine having the money do do that many project. heh

There is a strict physical limit to how large you can make a microphone capsule without running into acoustic phase cancelling from one end to another.

On the other hand, you will want as large an area as possible for high output/low noise.

The best compromise is around 22-25mm dia.
