I just rebuilt the only bakelite condensor block on this radio, a Philco 40-130. It now has two Y type safety caps. But the schematic (see attached) shows them located between the AC plug (now polarized) and the power switch. That means that these caps are always "on" with voltage across them whether the radio is on or off. Wouldn't it be better if they were after the switch?
I looked at a couple of other radios to see what they did. The GE E81 has their AC line caps in between the AC and switch. Some Atwater Kent and a Majestic 451 have it after the switch. I guess there's no convention.
