Mobile Fidelity inner sleeve problem - replacement suggestions?

Norman records in the UK sell the poly lined paper sleeves, and they seem a bit cheaper a low quantities than covers33. I am asking what they would sell a larger quantity for. Will report back.

And a typically speedy reply from Norman:

 

"Hey David

 
Well 100 would cost 30 quid if you ordered through the site. We'd do 'em for 27 quid if you wanted 100 though.
 
if you want to do that let me know and I'll ping over a 3 quid voucher so you can order 'em.
 
Cheers
Phil"
 
So that's now a little dearer than covers33 for 100, but I'm going to add these to a current order anyway. I like dealing with Norman and their shipping is very reasonable. These are black paper btw.

Interesting on the long Hoffman thread, people are going back and checking there records in mofi sleeves, and quite a few are exhibiting the similar issues.

 

Could you post a link to the thread pleae?

I was able to work out that I have purchased 6 packs of 50 MoFi sleeves (which is many more than I first though) and have about half a pack not used yet.

So in among about 900 albums there are at least 220 MoFi inner sleeves in use.

After checking through about 120 albums I have found 12 faulty MoFi sleeves and many MoFI sleeves that are OK.

 

So the good news is that it would seem out of the 6x50 packs (300 sleeves) I most likely only got one pack of 50 that is crook with these odds.

 

But the bad news is that nearly every record needs to be checked which means pulling from the shelf, removing from outer sleeve, then if MoFi sleeve is there, pull that out, pull the record out and examine under strong light. If effected I am putting a small coloured post-it sticker on the sleeve, repack record and back on shelf.

So once I have identified all the crook ones I can set up Spin Clean and wash those records and re-sleeve them in a couple of wash sessions.

 

The PITA is the checking part.

Here is a photo of what the faulty MoFi sleeves do to the record.

Difficult to get a photo as you need to get the light angle just right so you can see it.

If you look with the wrong light angle the record can look perfect.

 

The marking can be smudged if you rub it with a clean rag so it is some kind of residue.

Tried this in the run-out groove area.

If you then rub the inside of the sleeve you can just barely detect a slight greasy feel when compared to a non-effected sleeve.

i've been using these for well on a decade with the only problem being one or two that had a tear in them.

 

are the greasy ones in the original silver pack, the newer yellow branded packs or both ???

I am unable to say if they are the silver or yellow branded packs that have the issue.

I have used sleeves from both types of packaging and do not know which ones I used on what records.

All I can say is the last pack I have (which I purchased from Wyndham Audio Australia) is partly used yellow branded and they are OK which really tells us nothing.

 

The other 5 packs I purchased from Acoustic Sounds (mix of yellow and silver) in the USA along with large record orders in May 2013 and January, March, August and December 2014.

Quick scan seems the problem was in batches from around 2012? Maybe someone can confirm that.

 

I have a few packets, not sure when I bought them. I'm going to use a sleeve from each pack on a sacrificial lp and see what develops.

 

Any idea how long the "damage:" might take to appear?

Mine are from 2013/2014

If you rub the inside, especially inside the top side (with arrows) it will feel just very slightly greasy when compared to a good sleeve.

 

It also seems that the effect is immediately detectable.

Put a record in the sleeve, then squeeze the sleeve between fingers and then look at record under good angled light and if the sleeve is faulty you should see a mark on the record were the pressure was applied. Ensure you look at various angles as it can hide in the wrong lighting.

Thanks. 

 

I think the problem batches were produced around 2012. I'm not sure when I bought mine, or what batch they are from.

 

Did your test and it looks OK. But will leave them in for a few days now.

anything that is treated and makes contact with vinyl records has a habit of transferring at some later stage

that would rule out all inner sleeves as they are all made from processed materials

or are there exotic ones made from unadulterated materials with which to gently caress your vinyl ?

 

:D

I have been using the "MA Recordings" inner sleeves for a few years, pricey yet effective:

Incredibly soft, don't appear to leave any marks or scratches, perhaps I am naive and wasting my money, I have tried the Nagaoka and the MOFI, I find the MA recordings superior.

 

Audiophile reference recordings in Melbourne sell them locally.
