From the post
Found a bunch of Nine Volt Nirvana/Joe Gagan schematics on Fredd Brigg's blog. I'll probably do a few more of them, but first is the Tape Measure boost. Super simple and should easily fit in a 1590A. Original unit used a trimmer instead of an external volume control, but I figure most people will want the external control.
