It's one the ones made in early 1969..
If the jack plate on the speaker cabinet is etched with CTS then the cabinet is for Bass if it's still loaded with its original speakers.
Chances are it won't eliminate the hum, just a safety issue as far as getting a jolt if you touch something else metal and you become the path to ground. Bill or Stevem will probably tell you that its a capacitor issue or something along those lines. If the unit has reverb on it.....I can't keep all the amp heads straight......just turning the knob down doesn't shut it off and you need a foot switch to completely turn it off, at least that is the case with some of my amps that had a hum.

It will reduce any hum, in fact it will give you a Buzz tone that with the original two way you could stop, with a grounded power cable the only way to stop will be to touch the strings or something that's grounded on the guitar like the bridge.
But as posted you will be safe from the minor shock that we have lived trough.
