Hi Adrian,
The quick answer is yes, I traced out the schematic when I was chasing down a bit of background hum.
The slow answer is its in a box thats packed in storage. I'm just about to start some major alterations in the house and have boxed up all my crap (technical term from DTB) to keep it safe.
From memory its a standard aikido configuration, but I can't remember which way round the tubes were stacked. There's been a lot written about designing aikido's, and they are very forgiving, so its shouldn't take too much effort to figure it out.
