I purchased this Philco 48-250: As a practice set. My first.

And have a question regarding converting to a polarized ac cord. I have received differing opinions on whether or not to use a polarized power cord as a safety factor in this AC/DC chassis. Some say absolutely and some say keep it as originally designed. Also need to know if I use the polarized cord should I connect the + lead to the on/off pot or to the rectifier tube as the original non-polarized cord. Seen here:

According to Phil's Old Radios I should follow the procedure found here:

Any opinions?

Thanks for your help.
