Unfortunately, the set has the power switch in the grounded side of the line, which will make the chassis hot with respect to earth ground when the set is turned off.

To make such a set as safe as possible without major redesign, I would recommend the following:

Replace the interlock and cord with a polarized type.

Move the power switch to the hot side of the line.

Directly ground the neutral side of the line to the chassis.

Delete C85.

Replace C84 with a safety rated (X1Y2) ceramic cap.

Should that capacitor have the same capacitance as the original or just anyy capacitance.

Same as original is always best, but .05uF is a bit large for a ceramic type. You may need to go with a polystyrene film cap. Whichever you use, make sure it has the proper safety rating for across the line AC service.

This cap is used for RF bypass purposes, and isn't all that critical as far as capacitance value.
