Can you measure the ac voltage to ground on each side of the filament wires?

It's that time of year where I sit around and vegetate so I decide to do a conversion on a little Champion 600 I bought when they first came out a few years ago. It has always hummed about as loud as the maximum volume on the guitar so it never got used. I didn't want to spend a lot of money on magnetics and wanted to use what I already had on hand. Problem was, all conversion I've seen are done by changing out the magnetics and using a tube rectifier. No schematics or layout diagrams for what I wanted so I set about to design my own diode rectifier layout by searching the internet. Here's where I am at at this point of the project. My problem now is, I have found two different sources on wiring the AC power to switch and fuse. The old Fender layouts show AC going directly to the switch and then to the fuse, others show it going to the fuse first then to the switch. Hopefully someone here can provide the correct answer for safety. These drawings are done by me as an example.
Fabricating the circuit board out of left over Bakelite material fron another project. Will be drilling and installing eyelets
