I've also had a number of the PDO Blackburn 'brown rot' discs, and they
have replaced them all FOC when returned to them. However these don't
show holes. Just a brown discolouration of the metal.


I've never seen this first hand, but I have a number of older CDs that
seem to be deteriorating with age (visually at least - they still play
without problems).


Are they developing brownish regions? If so, check the info near the center
of the disc to see if they are PDO, also check the manufacturing date. If
they are, you may well still be able to contact the relevant person who is
dealing with PDO returns. When I did this (a couple of years ago) then
replaced the discs FOC. This included some 'free' cover discs I had from
BBC Music Mag.

I have bought a CD that had mould though. I'm guessing this was just due
to bad storage, and nothing to do with manufacturing. The surface of
the disc was mottled green. Very odd, as the case showed no signs of it.


Never encountered that!

However, as those who used to buy EMI classical LPs can testify, you can
make *anything* badly if you can't be bothered to take due care.

Slainte,

Jim

Thanks Jim. Some of them do have brownish areas that appear to be
growing. I'll try to dig one or two out and take a closer look - it
won't be immediate though, as most of the collection is currently boxed
up ready for a house move.

Ain't that the truth! Some of the EMI LPs I remember from years ago
seemed to be the 'extra floppy' weight of vinyl, that would bend under
its own weight.

I've got quite a number of EMI 'MFP' LPs as well as a large number of 'CFP'
discs and to say thay are all rubbish would be patently untrue. Many/most of
them are perfectly fine.

What's the record 'weight' got to do with it? - Appears to make not a lot of
odds on my kit....???

(Which does use a very heavy brass clamp...??)

MFP, is that the "Music for Pleasure" stuff? Actually I had a very good
copy of one of Tchaikovsky's Piano concertos on that label, which got
played to death. I wouldn't say it was all rubbish by a long way, I just
happened across a few bad examples.

Never mind the quality, missus, feel the width :-)

I've no idea if vinyl weight really makes a difference - these just
didn't feel like quality product. They came complete with lots of 'vinyl
shavings' across the surface, and generally didn't give the impression
of being well produced.

Oh I don't say you couldn't get some howlers in the MFP range but my
expereience is that there a lot of damn nice albums on that label, not to
mention some truly wacky stuff like Mikki & Griff and 'Dorita y Pepe' :-))

At just under a quid, they were the 'Naxos' of their day and I'm delighted
to have the ones I've got. (Wacky or not!)

Classics For Pleasure (CFP) is a slightly different ballgame - many of them
(I *suspect*) are reissues of more costly albums that were previously
distributed as 'top line, non budget' albums. I have an enormous number of
these and they are mostly quite excellent. Once again, an inexpensive way
for some pore ole soul to build a decent library for a reasonable outlay!!

Let's have some fun - email me with your (classical) Heart's Desire (Nos, 1
and 2) and I'll see how close I can get to it for you and will do you a nice
little silver disk..... ;-)

Well, my records are clamped like I say onto an acrylic platter so I don't
reckong to get much 'ringing' but I have to admit a nice thick 180 gm
Columbia or summat similar will put a smile on my chops for a wee while!!
:-)

Swarf, sharp edges? No we don't want them, but I'm not sure the curly ginger
hairs you get on a lot of charity shop vinyl is a much better alternative!!

That takes me back..Mikki & Griff toured with Lonny Donegan.. liked the
Lonny bit :-))

Me too, if there was nothing too tasty in the charity shops I'd always go
for MfP's, they used to be about 50p to £1 so ok by me. Now the shops have
got wise & charging daft prices...

Yes, its good fun comparing the costly albums with CfP :-)

Now that's just plain daft ;-)

200 gm even better.....

What do you expect if you buy bonking music :-)

Heh heh! Not my cup o' tea I assure you, but I have to admit I liked his
'Cumberland Gap'...!! ;-)

Which has achieved the rather nice double of killing vinyl flow both in to
and out of these places....

I mean I'm sure it's the exact same pressing in some cases!

Absolutely not - a good CD recording of an LP is damn near as good as the
real thing!! (Didn't anyone tell you that? ;-)

Plus it gets to save stylus wear, if it's a 'frequent flyer'....!! :-)

Stoppit......
