can someone direct me to a website that has a layout of a 12AX7 tube? I'm trying to mod an amp and I'm not sure which pin is which (and I will need this info when I build the Shaka Tube to).

The single best source I have found is the "Tube Data Sheet Locator" at:
http://www.duncanamps.com/
download the Personal Addition if you want the data at your fingertips. :D
Here are the results for 12AX7:

For common guitar amp tubes like the 12AX7, try this link:

You can find data from most parts (common tubes, transistors, etc.) at any search engine by giving it the name of the part and the word datasheet.
Take care,
