You're not looking at the right thing.
Is that one of these (see 3rd reply)http://www.ax84.com/bbs/dm.php?thread=434791I have a Stromberg-Carlson that my brothers & I carried home from the town dump way back in high school. Dual 6L6 push-pull output. Supposedly is only 50W, thing is way louder than my 450W Berhringer Bass Amp and doesn't make the speakers seem like they clip when a low G is played suddenly. I want to build something like that with these other parts.http://crossroadsfencing.com/stromberg_au-36.pdf Mine is a B, don't recall what is different, someplace I have a picture of the schematic that's in the bottomI built a High Octane kit from ax84.com before I started arduino-ing.Just not enough time in a week to do all the electronics I want, and fence too. Darn day job gets in the way!
