[TCML] 10 amp ballast

[Scott Bogard <sdbogard@xxxxxxxxx>]

Greetings all,
     Wondering if anyone has any "instructions" of sorts for a good 10 
amp 240V ballast that will last long runs.  I know 10 amp seems kind of 
small for a power supply needing ballasting, but my idea is to stack 
four of them in parallel to A. dissipate heat better, and B. to allow 
for some variable power in the stead of a variac...  I was thinking the 
welding rod approach, maybe a 1.5 inch PVC pipe, 2 feet long wrapped 
with x turns of 14 AWG...  Just not sure ballpark how many turns to use, 
of how much heat that will generate, hence what kind of cooling I will 
need for say 10 minute runs.  Input is appreciated!

Scott Bogard.
