Yes, you want the neutral side of the line to connect to the chassis.

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.
