Re: Best way to reduce Filament voltage?
Here is one trick that has worked well for me:  
Radio Shack has 50PIV, 6A rectifier diodes for $2.00/3 pack (IIRC). Take two of these and wire them "back to back" parallel. Then insert them on one side of your filament string.  
This provides a constant (i.e. independent of current draw) voltage drop of 0.7 volts. It's cheap, parts are easy to obtain, and it doesn't build up any heat.  

Major Pain Thanks for the info fellas. I think... -- 11/13/2003 4:35 AM
