Where can I find one?
This speaker otherwise is totally great - the cone looks like new and it is, I thinkk, original and the spider and all, and even the transformer is good and the whole thing looks great.

But (here flies in a fly and drops in that ointment) as usual, something is screwing up the idyll.
The field coil is open.

Now I want to know how to remove it and whether it requires then any tools to put it back. Does the central magnetic rod stay with the speaker and only the coil is lifted when that nut in the back gets removed?

I have an extra speaker from the 70 that I got supercheap (speaker and chassis from 70 for 15 bucks.....this is what Kutztown auction is for), of which the field coil is in an unknown condition but, should it turn out to be OK, I'd like to introduce it into my speaker. This would make an ideal tester for pushpull 90 and 20 outputs as it then would be fully original.

So....I remember someone somewhere discussing it. I need it in all small minute, if not miniscule, details - this speaker is so great that if I so much as nick it I will commit moral suicide. For a week. And my whisky bill will soar. And my liver will suffer. So...please consider this when you guiding me to the procedure.

No pressure.
