I'm looking at the 115vac mains connection to the chassis.
Now I have to mention that the IF strip, Tuner, and all B- is floating above the chassis. The IF Strip and Tuner are mounted to the chassis using nylon "clip" nuts and the metal plate of the IF Strip and all the metal of the Tuner does not show continuity to the chassis.
Here is a photo of the mains power part of the schematic. Resistor R58, 1 meg, goes from the "switched" side to the chassis. This is the only connection that I can see where the chassis is connected to the mains. C54 will be a Y2 safety cap, and C52 will be a Y2 safety cap. There are 2 more caps one from the IF Strip metal plate and one from the Tuner chassis that goes to the chassis. I'm guessing that these need to be Y2 safety caps too. In the schematic you can see one of them (C57 from the Tuner chassis to the chassis) in the upper R/H corner.
I've never worked on a hot chassis before, so my question is should I wire the hot leg to the switch and the neutral through the fuse and onto the rest of the circuit? Seeing it is AC does it really matter? Should I reconfigure the wiring to switch the hot leg and have it going to the fuse and onto the rest of the circuit?
I do plan on using a polarized plug for the power cord. I won't be using the provided interlock cord though. Also I'll be using my isolation transformer with this chassis.
