I would like to reinforce what Doug is saying here....rapid discharge of 
any capacitor is a very bad idea.

When I work on equipment that does not have bleeders on the filter 
capacitors, I add them...this is a permanent solution...I try to choose a 
bleeder value that will discharge the capacitor to a safe level in less 
than a minute...10 seconds is what I prefer.

The same is true of Cathode Ray Tubes...never discharge these with a direct 
sort either...you can get a real nasty surprise...
