'super tweeter'. The amp is also of rather lower power than most would
use. Again maybe only early ones had a mid range 'suck out' so beloved
of BBC designs of the day. In a nutshell, sound rather different from
the contemporary domestic version.

Well What was good for the BBC in the good old days was good enough for
most all audiophiles

Not really true. What is pragmatic for broadcast use may well be bettered
at home.

I'll give just one example. When your favourite FM service started in the
'50s, some listeners complained of HF 'artifacts'. None of which were
'agreed' by the duty engineer. The answer was simple. The standard
monitoring speaker in use then - the LSU10, with a Parmeko dual concentric
driver, didn't reproduce much above 10 kHz. Or 10,000 cycles per second as
it was then. ;-) Auxiliary tweeters were bought from a retail components
shop (rather like Maplin used to be) and hastily bolted to the grills.
