Members ksl Posted July 4, 2020 Members Share Posted July 4, 2020 How does one add a 3-prong plug to any of these 50's amps I've been talking about? Please be specific, & perhaps a rendering would be great. Be safe all~ Link to comment Share on other sites More sharing options...
Moderators daddymack Posted July 5, 2020 Moderators Share Posted July 5, 2020 what...no google? I did try to explain this to you before...basically, follow the original wires... the hot [which will now be your black wire] will go to where your fuse is, which eventually goes to the power switch and the power transformer. The neutral [white] will go wherever the other wire went, sometimes right to the xformer, sometimes to the polarity switch...but not to the power switch! The green ground wire should be screwed to the chassis...here's a couple vids... I disagree with some of what you will see, like not tinning the wires before soldering them to a terminal...but what you need to know is there in both. I also will replace the wire leads carrying AC current to the xfrmr with the appropriate color so If someone else works on it, they'll know which is which. You'll see the Fender replacement he ties a yellow to a black...had it been my gig, they would have been white...and all the hot leads would be black. I've done this [mainly for other people] plenty of times, so I really don't even think about it...once you've done a few, you'll get to that point.

Members ksl Posted July 6, 2020 Author Members Share Posted July 6, 2020 I'm getting smart, following everyone's advice, & installing grounded 3 conductor cords into some old 50's P.A. amps. I've watched ALL the YouTube videos, and ALL of them deal with guitar amps w/polarity switches & 'death caps', & I don't see any clear, definitive or consistent info. Okay, Green is GROUND,, some videos show the White Neutral going directly to one of the trannies, and the Hot Black wire going to the power switch then on to the fuse, & then to the tranny. Then others show the white neutral going to the fuse & the black hot to the On/Off,,, AND vice versa, w/white to the power switch, & black to fuse. These are old mono tube amps, & as I mentioned, no polarity switch or death cap. I don't want to be another toasted statistic, or fry anything.Thanks in advance for your assistance!BE WELL!!
