Hold an LP up balanced on two fingers at opposite edges - you will see
how much it sags quite easily. Obviously it doesn't sag as much as
that with six suspension points, but it sags much more than enough to
generate a huge signal.

The Hydraulic was designed for the thick'n sturdy pre 73 oil crisis
discs which are a totally different animal to the later floppies.


There's all sorts of horse**** to do with coupling/supporting records
(vacuums, clamps, felts, rubber mats, glass platters &c. &c.) and plenty of
followers of each and every 'theory' - you just go with what you like, I
find. And I have to say I have never been able to tell the difference
between similarly good recordings on the various thicknesses of vinyl - a
good example that springs to mind is a series of compilations called....

called....

erm...

heaves arse off chair and goes to look

'Reflections'! (CBS10034 to name but a few)

Which are on really *whippy* vinyl but which are beautifully recorded and
sound fine! (I might use that one for the Tic Tac Test later!)




I got a couple of lp's last week, a Decca ffrr from 1965 and a bog
standard EMI Columbia from 1966 and neither droops on your finger tip
test, on the contrary significant pressure has to be applied to deform
them.


And some will hang like an uncooked pizza - I have yet to hear any *audible*
consequence therefrom, but what were the records? I'm always curious!!
