3 volt audio preamp?

I have an FM transmitter project I'm working on using a VMR 6512 ICthat has a Vcc of 3 vdc. I've been trying to find an easy preamp for the front end with about a x10 gain adjustable with a pot. I'm only aware of the LM321 - any others come to mind?

Thanks!

Controlling relay via the web

Does anyone know of an article anywhere that describes how to control a relay/relays via TCP/IP? I'd like to use a PIC oe something via serial or USB so it wouldn't require the facilities of a whole PC with say a parallel port...

thanks
