I'm getting a peavey 5150 II tomorrow and heard that there is an adjustable bias to make it run hotter.
Is this true, and is it something I can do myself?
So this box arrives this morning with a nice gleaming set of JJ 6l6's and a selected set of preamp valve type things all reeady to be put into the 5150, plus a bias tester! yay! THis means I can now go forth and bias mod the amp, and then watch my charred body spasm across the floor as I ride...
