Does anyone know,

I'm looking at getting some cap nuts.
Does anyone know the thread size of the pins holding the laminations on a GXSE Edcor transformer?
The ones that hold the end bells on to the laminations.
So there are only four pins on a GSXE as it arrives from Edcor they go through the laminations and end bells just holding the whole thing together. I don't know if they are metric or imperial/unc etc.

Regards
M. Gregg

On the ones I have on hand, GXSE10 are 6-32 and the GXSE15 are 8-32.

Thank's for the info,

So that's 8-32 UNC?

That's a strange size for cap nuts.

They are a standard in the industry.

It's 10-32 that's the oddball used ;)
(opposed to the more common 10-24)

Cheers!

I'm not sure from where where the "10-32" comment came. These are #6 and #8 screws. But for #10 screws,the UNC standard is 24 TPI and UNF is 32 TPI. There is no UNEF standard for screws smaller than #12.

Thank's I'll have a look around everything tends to be metric over here. Even BSF or whitworth is regarded as "special".

Another question on the GXSE has anyone ever taken the end bells off, I was wondering what the speaker wire connections were like. I've had others in bits but never bothered with the GXSE. I'm going to remove from a project and strip but if the connections are wrapped into the core...

Are they tape and solder "PITA" (wrapped into the tape and varnish on the core) or terminated on brass connections /spades/rings and soldered etc.
I'm guessing they are the same as the XSE-15 but if anyone has a picture they can post?

I Emailed Edcor today,

This was the answer:
No it is not recommended that you remove the end bell you would disturb the gap in the transformer. Recommend that you cut the lead wires short and add terminals if you want.

So its terminate and extend..That would still work.

But it means creating some nut caps rather than replace the nuts.
So it seems Edcor regard GXSE as a sealed unit.
