Double the power of your Gobo

There's a really simple way to double the output of your Gobo. When you "bridge" the two channels such that one "pushes" while the other "pulls" you double the power. Of course, you are giving up a channel to do this, so you end up with a mono amp instead of stereo. Could be good for an instrument amp. Just use a SoloG as a preamp.
There are no changes to the power supply sections. Simply add two resistors and rearrange the input and output wiring.
