eth	Re: Variable Power Supply My breadboard:A transformer with lots of current capability. Dc ends up being 560v, then is reduced with pi filters and a 160v zener. The voltages change with diff. circuits though (except for the 160v zener usually). Any way I don't do any soldering - all breadboard. for the pots. and the tube sockets they sell, what I think are called terminal strips. They look like bus strips, but have 35 - five conductor points. These work sweet because I am a neatness freak. I soldered wires from the tube socket pin/potentiometer lug to the bottom of those metal contact things. Sorry. This way allows the wires that will always be there not to clutter your view. I bent a piece of #20 steel into a chassis with a hammer, a piece of angle iron, and 2 clamps. The power supply is completely covered and all soldered wiring is done here. I think the time taken was worth it. it is very durable, not in risk of electric shock as much and I can transport it to try out other cabs. hope this helps. peace -eth
