Rewiring power cord for CRT
Ok, so I run retro tournaments around the country. I have 60 or so CRTs, I take with me. One of the biggest nuisances is the cord tripping up and getting in the way.
My plan to fix this has been to cut the cord and put adapters on each end with the end running out of the TV attached to shell. Essentially, turning these TVs into monitors with detachable power cords.
The only issue is that these are 2-prong and finding an alternative to male/female replacement plugs for 18AWG 120V is difficult.
Traditional replacment male/female 2 prong plugs are fairly expensive ($4-5 total per TV), so I'm not keen on spending $240-$300 on this type of project.
Are there any 2-pin quick disconnect or Molex adapters that would be just as good and more of an affordable option?

Try wrapping the cables up and use extension leads?

Pretty sure that would cost about the same or even moreSyntax wrote:Try wrapping the cables up and use extension leads?

Re: Rewiring power cord for CRT
Are there comparable 3-prong cables available? If so, why not upgrade the wiring? I'm sure the only additional step you'd need to do is to solder/attach the ground lead to the chassis.

I wasn't really planning on opening up the shell. More like plastic welding the short end to the TVnmalinoski wrote:Are there comparable 3-prong cables available? If so, why not upgrade the wiring?

Re: Rewiring power cord for CRT
This is tripping when i) moving the monitors about because the power dangles? ii) Not when they're just sitting plugged in?
i)
2x velcro cable ties going up back/side of monitor either (resin) glued or screwed in. All power cables get a quick coil and strap in when moving.
Because it's going to be a similar annoyance with 60 odd loose cables you'll end up with having anyway otherwise - even after all your work rewiring you'll still need to tidy away the loose cables otherwise it's jumble cable hell. Not to mention if you've still got a bit of flex coming out the back, it's probably still long enough to get stuck under the tv (or the one next to it) when stacking/moving them etc.
ii)
Otherwise yeah extension cords/pdus that you can even screw in, plenty of slack, and minimise any cable runs along floor.
One's cheap, the other not so And yeah can't help thinking you'll still have 60 odd cords to untangle/tie up one way or another...

Re: Rewiring power cord for CRT
I don't have suggestions to contribute but I'm guessing that you run tournaments for Melee, so I just wanted to say thank you for doing such an important job in keeping that sick game going!
If it's for something else then I'd be very curious what it is though.

Nope never run a Melee tourney lolfernan1234 wrote:I don't have suggestions to contribute but I'm guessing that you run tournaments for Melee, so I just wanted to say thank you for doing such an important job in keeping that sick game going!

My company is called the Retro World Series. We basically do all other retro tourneys besides Melee

Re: Rewiring power cord for CRT
lol Well any competitive community that prefers to run their games on a CRT is still cool in my book
Re: Rewiring power cord for CRT
You could probably use these:
https://www.aliexpress.com/item/5X-Univ ... 26160.html
They are the same gauge as most two prong appliance power cords. Snip each one in half. Cut the cord coming out of the television leaving just a short length sticking out, then splice either end of of these onto the TV and the remaining power cord, respecting polarity obviously. That's about $2.55 per set you'd want to mod, and probably as cheap and easy as it's going to get for you.

Re: Rewiring power cord for CRT
Except the exposed end running to the power strip would be live, correct? Similar to a suicide cable.Bratwurst wrote:You could probably use these:

I was thinking these would work.

Re: Rewiring power cord for CRT
Could wire the exposed end to neutral. Still some element of danger, but you never clarified if the issue of tripping were participants stepping over the cords or just moving/storing the televisions. Either way, unplug the cord from the outlet first.thetallguy24 wrote:

The threaded connections you linked to would certainly work and are also 18awg.

Re: Rewiring power cord for CRT
If you are going to hack up the power connection, I suggest just mounting IEC 60320 connectors to the backside of the TV.

Re: Rewiring power cord for CRT
Yeah, but then I have to buy all new cables (or connectors) + the mounts, so that adds to the cost. I have to find a 2 prong version of that anywaysmikejmoffitt wrote:If you are going to hack up the power connection, I suggest just mounting IEC 60320 connectors to the backside of the TV.

Re: Rewiring power cord for CRT
Two prong versions exist; I know they were used for the Xbox 360 power bricks. I would still recommend that, if you decide to move to that style of connector, just go with the three-prong and wire ground to the chassis. Yes, it's more work; yes, it adds to the cost, but those cables are cheap and everywhere, and grounding the chassis makes everything safer.thetallguy24 wrote:Yeah, but then I have to buy all new cables (or connectors) + the mounts, so that adds to the cost.

Re: Rewiring power cord for CRT
To do this safely I think you are going to have to spend at least $5 per TV. Most quick disconnects that you see are rated for low voltages, and high voltage options tend to be pricey. If I were doing this, I would mount IEC C7 type receptacles into the body of each TV then buy a bunch of power leads at a thrift store or something.

Re: Rewiring power cord for CRT
I agree 100% with this. Cutting the cords and putting QD is going to be expensive to do safely, and ultimately still a half added solutionArthrimus wrote:To do this safely I think you are going to have to spend at least $5 per TV.

Re: Rewiring power cord for CRT
I ordered the ones I linked too. They're 18 AWG just like the TV cords and rated for 500V so we'll see how they do. I'll install them with solder seal heat shrink tubing and plastic weld them to the TVs so we'll see this weekend how it doesArthrimus wrote:To do this safely I think you are going to have to spend at least $5 per TV.

18 down with no issues so far
