Hi Mark

You should definitely follow the procedure on Phil Nelson's website (via the link you provided above) if you plan on using your radio. It will make it safer overall by making the HOT lead of the AC line switched instead of the neutral.

With the neutral switched and the HOT lead connected direct to the rectifier tube, the set is basically HOT all of the time. Using Phil's modification, the set is only HOT when the power switch is on.

Simplified explanation. I think you get my drift.

Edit: That is a very good set for practice. No rubber-covered wires - Philco used improved plastic insulation on the wires of their postwar models which has held up very well over the years. Not a lot of tubes, so it is not a complicated set. Best of luck with it...and be safe!
