Leading To My Final Request,,,,

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~

My specific advice, and I'm not being cheeky, is that you need to take your amp to a qualified technician. By asking this question, you are demonstrating the lack of basic knowledge required that will keep you safe and possibly alive. You are out over your skiis. Remember the disclaimer....Tube amps contain lethal voltages, and such and such. I have seen a guy wire the mains together across a switch and he did not know why the amp kept blowing fuses. An honest mistake, maybe, but one needs to be very clear about what one is doing where electricity is concerned. It's not a matter of if you get bit, it's when.

That said, knowledge is power. Study this:

Yeah, we'll have bacon for breakfast here soon enough

[zozoe]

Sorry to troll & who doesn't like bacon? Maybe this picture clear up any mystery & make the fix simpler. There's no ground switch, just the on/off switch on the left, & fuse holder on the right, both with remaining fresh wires. So, sticking with just a 2 pole Polarized plug for now, the black hot wire from the narrower lug on the new AC cord, will go the the power switch, & the new white wire will go to the fuse lug

?

I'm simply taking out the old power cord & inserting it to exactly where it was before, sound right?

It is not an acceptable repair. You have demonstrated that you don't know how to wire this. You didn't demonstrate how you intend to deal with strain relief. Also, by today's standard, it needs to be a 3 prong plug. You don't know what you are doing. Don't do it.

While you're at it, locate and remove the "death cap." That's the one you often find bridging one or the other side of the AC line to the chassis. Some may make the point that once you have grounded the chassis by means of a properly wired 3 wire AC cable, the death cap becomes irrelevant. Maybe so, but those old caps often fail short - iow they conduct between the AC line and chassis - which can cause fuse blowing and would definitely put the chassis at a lethal voltage if the ground isn't what it should be. Two snips & it's gone.

And - guys, we have a noob here all right but isn't part of what we do, to educate those who don't know? It may be a bit vexing to teach those same old lessons over and over again. Although he's got a barrel of questions z seems sincere and I wouldn't rate him as a troll, just someone who's starting out on the same journey we all had to. BTW I have some incredibly good bacon in the fridge, just in case.

Hiya Leo, good to see you around. This is a continuation from this thread: https://ampgarage.com/forum/viewtopic.php?f=6&t=33475, which is why Steve called the OP out.

He has been advised, but does not acknowledge the explanation given, instead redirecting to cajole members here to tell him how to do the conversion. I get the enthusiasm, but he has been warned of the risks of proceeding in the absence of adequate training. And given our absurdly litigous society, the very last thing anyone needs is his wife and lawyer showing up here looking to assign I Spilled Hot McDonald's Coffee On Myself blame when he kills himself because he simply will not take his amp to a tech. We're not doing that.

There are many resources available, and I posted the drawing above which clearly details the conversion (which was ignored).

Trolls are not always easy to spot. Hanging out with Lord Valve on UseNet for a while makes it a bit easier to spot them.

[pompeiisneaks]

Hehe, yeah, I think the obvious is obvious.

We are a forum for more intermediate if not advanced builders, and we've got someone asking beginner questions about fundamental amp safety and simple requirements they still don't grasp.

Or they're a troll.

Either case is a lose lose for everyone.

Thus why I tongue in cheek said "If you must.. DON'T"

zoezoe. You can easily google and probably watch at least a dozen online videos on how to wire up a power supply. If you can't figure that part out on your own, our explanations are likely to be worse, and give you a better chance of accidentally hurting someone. Please for the love of dog, go to a tech.
