Anyone know where I can find a rah board somewhere?
Mark has a vero (http://tagboardeffects.blogspot.com/2012/04/catalinbread-rah.html) - I dunno about a ready to go PCB - but there's an eagle schematic and a couple of etching layouts over at FSB on the RAH trace topic. Haberdasher might be able to set you up with an etched board from the artwork at FSB.
Haberdasher might have something on file. He did a couple for me in the past
I etched one from Plesur's layout "Prince Albert". Here is my blog post on it and I have a zip of the BOM and etch mask if you want to etch it yourself.
