Hi Jim,

I read about your PC mounting woes with Pots. There is a company called A/D 
electronics in WA that sells pots, swithces and jack OEM. Sometimes they 
have stock in USA that you can dip into and avoid having to buy a zillion. I 
used to buy in lots of 100, but if you're making a modular, chances are 
you'll need a lot of the same values anyway. One option is to decide on a 
panel format and go in with a few list members on an order. They sell 
offshore parts in a variety of qualities--I used to buy them at about 20 
cents a pop. Not Clarostat quality, but I never had any major problems with 

I can dig up a catalog if you wish or you can get from them. Let me know if 
you ned their contact info.
