Hi

i am looking for a 12v regulated linear power supply or wall wart w/ at least 800mA or more .
it would be preferred if it has a 2.1mm plug. ( i am not sure about the exact size of the connector )

please let me know  where to get one.
thanks

Elpac units are one brand.  You might have to change the connector or add your own cable.

The 220 is used for Squeezeboxes and you can get that type of connector here:

MCM (http://www.mcmelectronics.com) has this adjustable on sale for $15.00. Parts Express was recently selling it at $24.00. I know the Squeezbox folks are using it to replace the wall wart. I bought one for the bench because at $15.00 I thought if it was junk I wans't out much. Surprisingly good little device. Nice XFMR and very stable under load. I scoped it and the output is nice and clean even with noisy devices hanging on it. Good deal. For the cable you could run down to Radio Shack and buy a pre made and keep the cable/plug portion or just buy a plug and some hook ip wire and you'd be set.

And that MCM Power supply is linear?

That same supply is available from a few vendors.

PartsExpress has it here

They also offer a set of adaptors here

It is a linear supply. While it is rated for 2 amps it will get fairly warm if something draws over 1.5 amps.

I second the one AVnerdguy recommended , I have one which I use to use for a dac.
