I went ahead and ordered the multi cap electrolytics at 160v rating although the single 80uF will be much higher rating because that's what I have and the 35L6GT tube that we'll need.

As I was going over the schematic, I realized that the person who had replaced the electrolytics previously (using that duct tape for insulation) also tied the can's common to chassis ground in addition everything else that is connected to the point "X" in the schematic.  The brown common wire went around the screw in the chassis and then to point "X".

I remember unscrewing the connection that was made and the remaning wire on the can still shows the loop around the screw

I'm not sure I understand how it could ever have worked in that configuration but I'll leave that for Terry to comment on...
