U344 on the pink label (with a bunch of other numbers) as Tony said it
probably would. I didn't see a Philips or Mullard sticker. I've searched
a bit and saw U412/U418 on offer on the web but at 40-50 EUROs which
seems a bit much.

Regarding using video recorder output or similar: I've sent a pdf for
modification of the morley to "the BBC lives" (pdf/mod by. J.Damme)
which uses the composite video output of a TV or video recorder via
SCART. I've not tried it myself, and I'd prefer not to use any other
equipment than BBC+TT adapter to get the TT data.
