Philco 84 polarized plug conversion
#2

Yes, it is always better to have hot on the switch. The cap placed on the opposite side is also good as due to the inductance of the primary (the tubes not conducting) on the turn-on, it will not pull spark when the switch is closed or open.
The sch calls for 0.015uF, so the popular value being 0.01uF, this is what I use for Y-caps.
You could also experiment with adding X-cap across the line (I always do it with a parallelled 1M reisstor). In case you have interference to suppress.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
