It's a British "electrical slang" term referring to transformers wired
in parallel and having the primaries (and therefore secondaries) out of
phase. In this configuration the secondary voltage of the two
transformers are additive (as opposed to having the primaries in phase
providing double the secondary current).

I've never heard of this term being used with xmfrs before.  Only diodes
and
ignitrons.
