all have been sold.

i will do more when i get more coils in.



they work great i have tested everyone of them on my machines.
they produce a very strong alternating field.
they are from 30+ inch TV's i have scrapped.

they work as good as the big ring coils that go for 40.00+ dollars.

the pic shows the 4 coils for sale but you will get 1 of the 4 in no particular order as i send them out so don't ask for a specific one as they are all equally as good.


Peace

These are pretty kick ass!

I kinda want one just cause you used a pill bottle for the switch. May be tempted to buy one as I've got a little red one that's just not strong enough.
 
I bought one just to see what prescriptions he is on.

the label is off tho

interesting... i'm in the market for a coil myself to address an issue.

pete why because of the pill bottle? did i really make you miss the 90's that much when i was over?

thanks they do rock.

the pill bottle makes a excellent insulator for the wires and is easy to hold.

and sorry they have been cleaned inside.:p

I made one last night and it worked. woohoo
I used a coil from an old Samsung tube I swapped.
Added the switch and an old extension cord. Wrapped it in tape

It did get very hot, very fast. I only had it on for a 5 or 6 seconds. Tape was starting to get gooey.
I saw that adding more coils will help this.
3 total? the more the better? Do you just add them in series? or parallel?

edit: Im hoping parallel, since that would not require opening up the old coil tape /cover :p

If you need a manual degauss tool, buy one. (Or better yet, just use a corded power drill. Google it.) Using a coil like this manually is a fire and electrical hazard.

When the coil is in a monitor, it's connected to a circuit that will only run it for a few seconds, and it tapers the current off quickly (so the full current is actually only present for a fraction of a second). There's a reason for that, and it's because you're sending 120V into basically a short circuit (i.e., the coil of wire). It has very low resistance, so you can't run power through it very long or else it will melt, as you're seeing. Adding more coils in parallel will just make them all melt just as fast.

Don't mess with this unless you really know what you're doing. There are easier and safer ways to manually degauss.

No inline resistor? My home made coil has a light bulb for this very purpose.

Using a lock on type switch is SUPER dangerous for something like this. You'll notice that the ones buffet made all have momentary switches.


The coil on a monitor is only on for <1 second. Any longer and you run the risk of it melting the insulation off the wire then you'll be holding an Arc Flash hazard in your hand.
 
so, put it in parallel? :whistle:

seriously though, I have one on order. heh

Like I've said before.... for the amount of time and money we spend in this hobby don't cheap out on HV tools... get a good HV probe and Degaussing ring. Tools that you will use a ton and protect you from 20,000 volts. Lol
