New failure mode with SSH1, while probing the output mosefet I slipped and the voltage stuck at -20V in, CCS was fine. So I replaced the MJE350, no good, the second mosfet, nope, then the jfet nope now it is putting out less than 10 volts now, check the potentiomter and it is stuck at 34 ohms, no amount of turns changes it. All my mosfets are zener protected, so I can't figure out how this happed.

When I find a replacement 1k pot, will probably replace all the sand again. Would wait on SSHV2 boards but can't go that long without tunes

Default SSHV2 guide

Hi guys, I wrote it finally. Its short but to the point I hope.
Since enough builds went OK by now I feel its cool you can go GB as you asked. I had only designated a bit different trimmer values (and their parallel resistors values) for easier handling as minor changes.
