July 1959 p93 has a review saying that the ESL had just started to be
imported.

There's an index in each December edition, which might help.

FWIW This is a way people can join in and help us with the ukhhsoc project
if they are interested.

If Phil or someone else can find the relevant details of an undated item in
an index/reference like the above and point us to that index/reference we
can then confirm it, and I can then modify the file name of the scan on the
website to show the relevant date. And eventually add textual info to the
site giving info.

Similarly, if people can find references that tracably date catalogues,
leaflets, etc, we can note that in a similar way.

One reason I felt it was best to get scans public sooner rather than later
was precisely that it enables others to help with finding out such details
if they are willing.

But failing anyone else doing it, I intend to when I get the round tuits...

** Found it, in November 1960.

The review is by "Hirsch-Houck Laboratories" an audio test lab run by actual engineers. They clearly realised the Quad ESL was in a class of its own.

Must have ****ed off a lot of the US advertisers that kept that Hi-Fi rag going. Never mind, other came along and thoroughly ****ed on it later.

" Sounds thin and metallic " & " Looks like it was built in a Bronx garage " are words I recall from a famous US subscriber magazine.

Thanks very much for that info. :-)

I've added 'Nov_1960' to the directory name and modified the index
page for the section to show this.

To be fair, that's true if your standard is Bose.

Odd comment, given the design of the average US car of the day.

To e-mail, change noise into sound.

Just to let people know I've been continuing to add items to the ukhhsoc
"Audio Documents" collection at

http://www.torrens.org.uk/ukhhsoc/AudioDocs.html

Most recently, I've started new sections on Sonotone and Celestion, as well
as adding items to the Richard Allan, Leak, Radford, Goodmans, etc,
sections. I still have a 'queue' of items to scan and add, but as before,
if anyone has any audio documents they can let us have, please let me know.
We want to cover as many UK makes and models as we can.

Cheers,

Jim

I've just put up more material. In this case reaching back to 1936!

Prompted by an email from a BVWS member and someone who has one of the
old chassis I have added some scans of old blueprints, leaflets, etc. If
interested, they can be found via

http://www.torrens.org.uk/ukhhsoc/ma...ous/index.html
and

I wonder if any current 'High End Audio' fans though that using
'Transmitter Triodes' as audio output valves was a new idea. If so, some of
these documents might come as a surprise. 8-]

There have been a number of interesting circuits
published in fairly recent times, using
"transmitter triodes": 834, 813 and the 833A.

A colleague of mine designed his own Class A
single ended amp, in zero global figuration usinbg
QB5. He built a dozen or so of these.

Transmitter tubes/valves were made to a very high
spec in large quantities, for broadcast and the military.
They are still available NOS at very reasonable cost.

I remember a long time ago new when worked at Pye TVT they used to use
DA100's IIRC in high power PA distribution PA amps and also in Band 3 TV
Sound modulators;!

The venerable QB5 can dissipate 565W so as a single ended
Class "A" triode one can easily achieve 120W.

Who said SET is for wimps? :-)

I'm thinking you could probably make a hybrid car based around a steam
engine. The question being why would you bother?
