Michael Aspel and PMC?
The other night I was watching 'Antiques Roadshow' on Dave, and they showed extracts of Michael's last show. Anyway, he was presenting from a boardroom of a Palace (don't know where, possibly Hampton Court) and as the camera panned round I clocked a pair of TB2s. They kept flitting back to Michael interviewing famous people, amongst a montage of clips from his stint, and the camera kept zooming in on these PMCs.
Also, on BBC News 24 they have a late night programme, think it was the 'Today' with Evan Davis, and noticed some Dynvector or Dynaduio speakers in the background.
On the 1970's-80s cop programme The Professionals there's an episode that shows a Yamaha CA-710 and possibly a Dual or AR turntable. Later in the episode they show a Hitachi D-220 cassette deck.
Have you seen programmes, either documentaries or dramas, with a recognisable hi-fi components?
