Greetings One And All. I sincerely hope all our members and contributors around the world are well and healthy. Very Trying Times indeed.

I've been absent for some time now. I'm sure I'll have o ton of interesting reading here waiting for me. .

I have been fortunate to be granted a superbly well looked after pair of 1 owner KEF 104aB's. In early pair I assume, sporting grey connecting terminals rather the more common black ones that I believe came later. (Can anyone confirm this assumption to be correct?).
This set appears to have had the T-27's replaced during their lifetime. The owner said he recalled one being "upgraded" in the past and this is evident since it sported a protective screen ala LS3/5a !
But there's more mystery here. I note that both T-27's have black wires to the voice coil. not the usual Blue / Black. Doubly interesting is these tweeters have no markings whatsoever on the rear, no date codes, not even a model number. There is only a small green sticker with the letter E imposed.
I recall reading somewhere that black wired T-27's indicate a very high degree of specification adherence and were used especially in LS3/5a's. Is it possible these a special version of the tweeter?

Can anyone shed light on this anomaly?

I should add to the post that these tweeters sound very good indeed. I have not done a DATS scan, but neither am I in any hurry.
The speakers both look and sound better any of the many pairs I've previously owned or worked on for people.

Didn’t they have a DIN speaker socket between the 4mm banana sockets too?

Yes, dead right, forgotten about DIN speaker sockets! Soldering heavy duty cable into a DIN speaker plug was fun. All those amp amps within a mm of each other
