Just confused on the wiring of the main double smoothing cap can. The connection from the half wave rectifier cathode (pin 7) goes to the one capacitor, the second pin is connected to a 5kOhm resistor , with wires disappearing into the depths of the chassis. Measuring each cap pin to chassis, gives a reading of 70mF, and across the two pins, the reading is 35mF. These appear to be connected in series? I'm wanting to replace this can with two individual electrolytics, but am not sure of the configuration. Would the can of the original caps be common, and connected to the chassis? I can only read 0-50 mF on the can, but I assume it says 50-0-50mF?
Very confused.

Any advice most welcome!
Thanks.
