Pink Floyd Reissues
I haven't seen the Debut alignment protrator but usually they all work off the same principle: slot it over the spindle and check the cartridge's alignment against two grids, one near to the outer edge of the gauge and one near the centre. Adjust the cart's position in the shell until ut appears square-on to both grids.
And I just check that the cartridge is parallel to the lines?
I seem to recall I did this last year and the cartridge was dead straight in the grids. I'll do it again as soon as I get a chance and confirm it, though...
Thanks for everyone's help! I'll be back to confirm/deny the alignment in a couple of days... 
And I just check that the cartridge is parallel to the lines?
My guess is that the record is damaged from abusing it somewhere in the past. I resurrected the TT from my dad's shed, so who knows what gunk was on the old stylus! New records play absolutely fine with no inner grove distortion at all, so it must be the record. Shame, though. Either way, I'll put it down to bad experience and learn from it!

Will still check the alignment though!
Ah ok ,now we appear to be getting somewhere. Have to say i had my doubts that you were hearing igd. This is why i asked the question if this was the only track/album you have problems with. Something you mentioned earlier in the thread got my brain cell questioning your interpretation of igd. To get it on just one part of one track, all other albums fine, read to me that you were actually listening to a goosed groove wall and what you perceived to be igd actually isnt/wasnt. Damaging the last 30 secs of an album groove takes great skill,well done 
Are you saying my record is damaged? If so how could I have done this?
Also - what's your definition of igd?
Thanks!

No you did three posts up the ladder. But it could be !.
I think you should do some homework on igd , its a minefield out there so take care.
But i still cant get my head around your 'distortion' is only audible for the last twenty seconds *.
Are you sure its not the heartbeat
.
* first off you stated the last track , then the last minute, then it ran into seconds. Hopefully you can understand why im having problems with what you are actually hearing thats not quite right.
Have you actually ever cleaned the flipping album, just out of interest.

Whoops nearly forgot this part Chris.
Well exactly as it says on the tin, distorted,spitty,muddy,generaly rank.
99% of the way to ( audibly) eliminate it,imo, is all down to cart set up and cart/stylus type. Tbh ive never ever had any problems at all but ive heard it and sorted it out for a mate. Bad set up from day one.
I'm sorry if I was being a bit unclear. The distortion happens (and by definition of distortion, I mean exactly that: distorted sound that lacks any sense of clarity; muddled, distorted audio that just sounds terrible, crackly and mishapen) at the end of track 'eclipse' at about the last 30 seconds mark (always in the same place on the same record).
I think this is because the record is damaged (as other records don't do this), so my original post was about good replacements for that, but I guess it's gone down into the route of learning about igd, and checking my TT setup (which I haven't got round to yet, but I promise to do it!!
)
So I'm finding this post to be very useful and insightful to me! 
Mornin Chris.
It really does read as though you somehow have some groove damage, which is a shame but these things happen. Maybe, just maybe, there is a stubborn piece of muck clinging on for dear life in the last few grooves , give it a damn good clean,you never know your luck, although its a long shot.
Dont boil your brain about igd , if you have had no problems with other records then forget about it and just enjoy your records.

Hiya,
I am about to order a disco antistat cleaner, so looking forward to seeing how that will improve my records. Yes I think if it was true igd it would happen all the time and be really noticeable on all the records. So I'm hoping it's a bit of muck stuck on the grooves... 
Thanks ever so much for all your help so far!

Not a problem Chris. However, alongside the Disco and its supplied fluid , try to get hold of some isopropanol fluid and if you are in a hard water area get some pure distilled water. Mix it 3-1 or 4-1 ( in favour of the water !) dosnt really matter. After you have cleaned with the disco fluid go through the process again with the prope mix.
There used to be a prope seller on the bay of pigs.
As i said its a longshot but if there is something stuck down there, and it dosnt have to be much, then your stylus wont be tracking properly and just bouncing around like a good un.
It could also quite easily be a teeny bit of rubbish in the vinyl, that no way on this planet could you see. Record companys have a nasty habit of using re-grind vinyl which can contain ,well pretty much anything really. Bits of label, fag ends you name it.
So really there could be any number of reasons why the cart isnt tracking correctly but a record cleaner,of some form or other, is a good investment at the end of the day.
slightly off topic,but can anyone review the new mixes of pink floyd on cd?

Hiya,
With the debut 2, the tracking weight is fixed, i.e. it can't be adjusted. The antiskate is on the middle setting which i think is right.
THe TT came with some kind of alignment protractor, but I'm not sure how to use it. The TT came set-up out the box.
If I posted some pictures on here would people be able to help me with the alignment? I won't be able to do this tonight, but I may have some time on saturday morning to take a look at the setup more closely.
Chris.
