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
