OK, so when I asked about the bias setting on the Lumleys, Keith suggested
that the owner should be running Svets in there, as did several others, so
I went looking for some sources and prices. Watford Valves have some "
Cryo - Treated " Svet 6550C's for a couple of quid more than the
'standard' types. See

This is a new one on me. Has anyone tried them ? Is there really any sound
or performance improvement from them ? Or have they maybe been cooled in a
big vat of the snake oil that everyone on here is so fond of talking about
?

This is an interesting one - another example of 'belief mechanisms' in
operation, but one where I *don't believe* it works. I don't *know* because
I haven't tried them myself, I've no intention of trying them and, worse
yet, I wouldn't *believe* anybody who did try them and said it did make a
difference!!

From what little Physics I do remember, I thought it was quite the opposite
of "At very cold temperatures (below -312°F), the molecules will align in a
more uniform, compact structure through the removal of kinetic energy." - I
thought the only way molecules could move in solid objects was if you
*heated* them up!
(Which is why blacksmiths ring the anvil when bashing red-hot metal about -
to 'jiggle' the molecules!)

Also, FWIW, if someone flogged me 'Cryo' valves I wouldn't even *believe*
they had been so treated anyway - how many fridges go down to -312°F...???
(Oh, OK - most valve dealers have got a cryo plant out in the back somewhere
then?)

(WTF is "CYROGENTIC" [sic] anyway - a proprietory name or one which
*implies* the real thing without being the real thing - like 'Mapleen
Syrup'....?? :-)
