Is there a value in QUAD II amplifiers?

Quad valve amps for some reason were pretty rare in the BBC - at least
in the TV side. Mainly Leak and Sound Sales. But they certainly made
up for it with the Quad 50 - TV theatre in Shepherds Bush, now The
Empire, had over a dozen of them in the early '70s.


The BBC also had their own valve amp, the LSM/8 which was a
derivative of the Leak TL12. These were plentiful second hand
at one time.

If they had used Quad valve amps in quantity they'd have given it their
own designation too - the BBC always did. Can't remember the
identification they gave the Quad 50 in its various designations. The BBC
Leak amp still wore its Leak badge, though.

Yes. I am sure you are right.
But if it were a standard amp (the prof model with input
transformers) would they have done so then? I recall seeing quite
a number of Radfords at BH, also with bal line transformers. These
had the Radford badge (of course they might have been known
as something else)

That is certainly so for the TL12, but the LSMs that I have seen
had no badge expect for the BBC engineering workshops plate
front left.

I know several ex-BBC people who read this group. Hopefully
one of them will make contact by e-mail, and put us in the picture.

Yes. That's the fella. That one seems to be in the Leak hammered
(was it called "crackle"?) gold finish. I have also seen them in grey
without the attenuator on the left hand side of the front panel.

Fascinating stuff! But don't his overuse of inverted commas and
misplaces apostrophes grate after a time! You get a (doubtless quite
erronous) picture of an old-timer who is pedantic, meticulous but
WRONG :-)

You did. I went back a few levels to look at the rest of this
facinating, though ungrammatical site.

Thanks Don. Interesting link. Note both the Bulgin mains
socket and also the XLR (Cannon) speaker connector, which was
also at one stage used as a power connector. Neither are
approved these days.

What colour where they? The Leak amps I remember from my BBC TV days were
all Leak gold. BBC amps were all BBC grey - or whatever the contemporary
colour was. But those Leak amps certainly had balanced inputs - I assumed
as supplied by Leak to special order.

Of course later on they used Quad 405s for the LS5/8 which were specials
with crossovers built in - so it might make sense to remove badges to
avoid any confusion.
