Hi Bill,

If you put the caps in series, you will half the capacitance and double the 
voltage rating. If you put them in parallel, you will double the capacitance 
and half the voltage rating.

The problem is that the only way you can do what you are talking about is to 
isolate one of the cans from ground and then you will have to cover it because 
the exposed can will have HV on it. This is not good practice if it can be 
avoided, although it is done all the time. That is why you see those cans 
mounted on a bakelite wafer with a cardboard cover in the can itself.

My suggestion is to cut one of the bad caps loose and leave it mounted for 
cosmetic purposes, then mount one of the dual sections where the other bad cap 
is and wire it acccording to the circuit. Cut the terminals off the bad cap 
that is left on the chassis so that if the unit is sold and needs service, what 
you have done will be obvious to the next owner.

I am curently recapping a P-2000 supply for the SR-2000.  Talk about 
fun......!

Remember to keep one hand in your pocket and teach your kids that when they 
dial 911, they should tell the dispatcher right off that this is no drill!
