Hi, would it be at all possible to home build a tube DI box? how would I do it? Would the valve go before the transformer? What kind of valve should I use, would it need a power supply?
if you have no luck building one these are used by so many pros it's not funny.. http://www.countryman.com/html_data_sheets/t85data.html
http://www.jensen-transformers.com/apps_sc.html Check out the first output line driver schematic. You'll want to do some creative adaptation for use in a typical DI application though.
