Hi Guys,
Tom - If you can mod it for a trioded 6EJ7, go for it!
Personally I would either make an adapter, chopping traces is a headache even for experienced folks.
Bill - Intro cost: $25.50 for either octal or noval version. I'll par it with the KTA board ($27.50) after the first run is done.
Artwork is proprietary to my partner. The circuit is "Copyleft", so if you reverse engineer a Gerber for it, you can post/redistibute it at no charge.
I'll work on a BOM first thing Monday (I'm entertaining tomorrow). I usually wait until I work on the documents, but I'll fast track that one ;-)
nyazzip - Two reason's I don't bother: 1) I have a symbiosis with my partner for PCB's and 2) the quality level of the work his professionals do would cost three times as much from any other factory.
Cheers!
