loose wire on my power transformer, where does it go?

[embotone]

I removed the end bells to repaint and found this wire loose inside.  Should it attach to the flux band?

[DummyLoad]

is the amp working?

yes: snip it off & 86 it. :-) it probably attached to one of the end-bells post a pic of inside of the end-bells, unless you painted the insides, then it's moot.

no: you have bigger fish to fry... pun intended.

Is that a broken wire in the red circle?

This wire is comming from the body of the PT . no need to be connected IMO

[embotone]

This transformer has been on my shelf for years, but did come out of a working amp.  I may have pulled the wire loose form something when I removed the end bell.  I can't see anywhere that it may have been attached, definitely not the endbell, looking at it with a magnifying glass.  There doesn't seem to be solder on the wire, though the end is not a clean cut, more like it was pulled off of something.  the wire goes under the top laminate and then into the windings.  It does have continuity with the top laminate.

[stratele52]

IMO this wire may soldered to the copper foil we see ( it have solder too)  . It have solder at is end and it is grouded betwee laminate

[PRR]

I would carefully pull it out and throw it away.

I do NOT like the way the short end brushes the winding. It doesn't seem to connect, so it is likely to vibrate and wear-through the insulation, cause a short.

While it may be part of the grounding, it doesn't seem to be done right, guitar OTs don't really need a lot of internal groundings, and loose grounding can be real trouble.

[embotone]

it does not just "brush" the winding, it is attached to something in there.  By the way, some may have noticed I painted this thing blue.  That is to match my Edcor output transformer.

OK, yes, but that's with the end bell off.

Looks great, you did a very nice job, but if that wire kills the OT, what difference does it make?

Willabe, I am not sure where you are coming from.  Are you suggesting that when the end bell is on, that wire won't be connected to somewhere inside the windings?  And I am not bragging about this transformer looking great, I was just explaining why there is blue on the windings.  You are right, if that wire screws something up, the transformer is trash.  That's why I posted in the first place
The length of the wire seems to suggest to me that it was soldered to the flux band.  but I don't see any evidence that it was.  That is all
I know.

What about that Embotone ?

[John]

Just to clarify for myself, is this your power transformer, or output transformer? It's being called both.

Title is Power .I would be surprised if this is a mistake. Regarding answers there may see a name errors

[Willabe]

I read what you wrote wrong.

But you still will have a loose end flopping around in there.

I guess what I will do is tape or shrink wrap the loose end and put the transformer  back together.  If I have problems when the amp is done, I will pull the end bell off and solder the wire to the copper shield, as I don't know where else it would go.  I think that wire was  loose/unattached since it has been in my possession(34 years) and it certainly used to work.

There is a soldering stuff on this wire or it is the picture ... ?

If yes , why soldering stuff if not soldered somewhere ?

[embotone]

I don't see any solder on the loose end of the wire using a magnifying glass, but it may have been a really poorly executed solder connection to the copper shield.

So it this the photo / lights , it not real solder .

[embotone]

that is correct, sir

[sluckey]

I think that wire was soldered to the shield as indicated in this pic...

I agree with you and that is what I write october 10  ;
   
 

[stratele52]

Maybe this wire solder to the copper foil will remove electromagnetic field from PT ?

[sluckey]

Transformer must have electromagnetic field to work.

[stratele52]

Transformer must have electromagnetic field to work.

Yes it have if not do not work    I mean to ....to keep or send EM field to ground .

I' m french Canadian so my english is very poor.

[sluckey]

I knew what you meant, but I just couldn't resist poking a little fun.

Hi Embotone
I noted a similar loose wire when I took off the bells of a power transformer from a power unit from a 1948 jukebox.
I too noted a bare, multi-stranded wire coming from about midway through the windings. Mine does not look broken nor soldered and there no indication that it was connected anywhere.

I'm wondering what you ended up doing with the loose wire and if the loose wire had any effect on the operation of your power transformer.
