Newark Electronics carrie replacements for the Cinch-Jones connectors used on the power cord. The hood is not metal but is plastic instead. The original cord has a panel fuse holder in the hood.
The Replacement connector has enough room to mount a panel fuse holder in it (on the side of the hood) so make sure you do that to protect the power transformer and have a safe unit.
I have built several of these power cables and use a three wire power cord for added saftey. Computer power cords make great low cost three wire power cords and are cheap at thrift stores.
For added protection of the power transformer I would replace all the electrolytics in the power supply Newark also sells them.
Here's a great site on why and how to replace the capshttp://antiqueradio.org/recap.htm
the manual is available for free download on the net (bama.sbc.edu ?)
