I'm not surprised, because it was probably a term made up by Broskie...Never heard of it. Link?
Would you know where it was first used?Quick google suggests it's not a Blumlein design, but the Garter circuit is well known.

No but some tube lover called Merlin (I assume Mr Blencowe) did state he had done some research into it's history. Hopefully he will pop up.

Hey, let's not drag poor Blumlein's name through it. I don't know how Broskie accidentally attached Blumlein's name to the circuit, but the garter circuit was created by Jean-Victor Martens in patent FR64203E, not by Blumlein!

Oh, please stop calling it the Blumlein garter, Blumlein never used it! It was patented by Martens in 1949 (FR64203), and transformer coupled versions even earlier (US2204578). But Blumlein had nothing to do with it!
