[DSP-10] Files for Brickette PCB

[Bob Larkin]

Thanks for catching the vendor confusion, Mike.  For Mike's files in 
bricket.zip, I meant to lead to the company ExpressPCB, but didn't.  In my 
mistake, I accidentally listed what looks like possibly a good source for 
PCB using Gerber files. OK, let me try to summarize, and others may add to 
this:

If you use the Gerber files from
http://www.proaxis.com/~boblark/amp2.zip  you should be compatible with
AP CIrcuits, Calgary, http://www.apcircuits.com
PCBExpress http://www.pcbexpress.com

If you use Mike's files from
http://www.proaxis.com/~boblark/bricket.zip you should be compatible with
ExpressPCB, http://www.expresspcb.com/index.htm

Prices vary amongst the vendors, and the quantities ordered.  The Gerber 
files include solder masks and top silk screens, but for small quantities 
there can be big savings by not using these. The QST article was done on a 
board without these layers.  Also note that this amplifier board has almost 
solid ground on the bottom layer, and does NOT (even in production) have 
bottom solder mask or silk screen markings.

Ordering instructions are on each of the web sites listed above.  I have 
ordered from AP Circuits, and Mike has ordered from ExpressPCB.  We have 
both had good experiences!
