Know any photographers with a high end high res printer. More than enough res for a driver, I'm certain.:wink_face:

Some braniac could probably whip up a thing out of a few old floppy drives....

So a couple years back I see these "Fostex T10"s on Kijiji for $20.  They look to be in mint condition, so I google it up, and see all kinds of you folk are loving these old orthodynamic things.  Of course, for $20, it was a no brainer.

 

My first question is for this guy: dBel84, I've tried to mod them in a similar way to yours, due to the fantastic measurements on Innerfidelity.  But what in hell is a "Smeggy Felt", or a "Yellow Biscuit" or "Aussie Felt"?  Cause you get some odd looks asking around fabric stores for smeggy felt.  I ended up using material that I thought looked similar, and the end result is quite good, but I've always wanted to learn more about how you did the mod.  

 

My next question is for all you Ortho nuts out there.  I really love the sound of my T10's, but I can't put a finger on why.  They have a small soundstage, and I generally hate closed cans, and they are a bit of a hog to drive.  The T10's sound quite neutral to my ears, they don't have a lot of bass but it reaches quite low.

 

 They clearly sound different then my Sennheisers, Grados, Koss, and Shures.  The T10s sound worse in a lot of ways, but when I listen to Silent Shout by the Knife, none of the other headphones make me dance like the orthos.  I can tell they do something really well, I assume it's the unique technology, but I can't put it into words at all.

 

 So what is it that makes orthos special?  What can they do that clearly separates them from dynamic driver headphones?  Why, in spite of short comings, do I still keep listening to these things with some genres of music?

I would love to be there. Those are materials from modders. Some of which are made no more.

:)  sooo tempting to have some fun with this 

 

smeggy felt - just thick but dense felt initially used to damp the now extinct SFI drivers by our own ortho nut "Smeggy" who gave us the 'thunderpants' and opened the doors for all further T50rp mods including Mr Speakers Mad/Alpha Dog and LFF's Paradox. It is a thick natural fibre felt pad ( not unlike old carpet underfelt ) 

 

"yellow biscuit" , this is not what happened to the Blues Brother's Rubber biscuit after a decade of sitting under the fridge. It is the glass fibre pad that is found in some of the early generation fostex and oem's.

 

Auzzie felt = discovered by Ludoo in Italy , a dense yellow felt made from australian sheep wool , very good natural damping fibre 

 

sadly - all of these materials now only exists in various modded headphones around the globe. I know I have nothing left , there might be a swatch lying about in somebodies toolbox 

 

The magic - the clarity and natural essence of the mids. However tuned correctly, I would take these over the majority of Sennheisers, Grados, Koss, and Shures ( and do )

The T10 is possibly the only ortho that I have really regretted trading away.

post #22509 of 23692
You have said that several times, Armaegis..if you really regret that bad, why dont you grab em back ?
*take a deep look at my avatar wont help... tongue.gif




speaking of T10, last week the right channel of my son's T10 suddenly just stay silent when hooked up to my ipod...
i asked my 8th years son, if it been dropped or such things lately but he insist do nothing harm to em...
so, i thought its a solder joint problem on the neutrik 3,5mm..so i reterminate it to a brand new gold neutrik..
its just stay the same, the left channel doing just fine but not with right channel...
so my guess is, it has to do with the solder joint inside the cup housing..
even if i can't see any sticker mention its use alum solder, i believe it is the same as other T10's..
i dissasemble the right cup and see are the cable cutted or not, well it stick to the solder joint..
but i can only hear very very small sounding from it when playing songs from my ipod..so i believe the solder joint has loosen...
how sadly...frown.gif

after several days thinking what to do, alot of googling and several youtube's video..now i know what to do with em...

i remove the cables from the right driver, dismantle the trace film+solder pin rings from the capsule+magnets, clean the solder blop from the driver pin completly..
add a fresh of car machines oil to the holes of the solder joint (dont let em near films), put the cables back to holes + -, then solder em regularly...put them back to the magnets+capsules, and WALAAA!! its sound just like a brand new...my son's T10 are normal now...

*this is how it look when dismantle the capsule driver..for illustration only, cos this is the pict of left channel driver..






so, its what they called alum solder, eh ? therefore i really feels that i have to share this with all you guys...
we dont need to purchase any expensives alu solder on ebay or do some other tricky steps to solder the loosen joint on T10's..
all we need is a fresh oil, refer to car engine's machine oil, adds a little amount covering the holes of the solder joint, no need to use the oil too much though..just remember not to let any fluid come near to the membran/films, i have warned you..keep safe, guys ! wink.gif



note:
the impression using these pads are diff story...at least its very comfy for my son...

I hope what i sharing here can be a good tips for the beginner/electrical noobs like me...
and sorry for my bad english, english are not my native language..tongue.gif

Hmm, finally tried this felt (wool? foolt) piece from a winter coat that a local orthomodder gave me to mod my YH1. IIRC he said that to use just that inside and replace all of the stock damping. Well, not confident on how well they will stay put when I put everything back together, I lined the cup with those thin generic foam sheets, and then the foolt pieces.

Hmm is all I can say right now. TBH I don't know what I'm aiming for with the mod for now. For a long time I like the stock YH1 sound, but I just felt my hands itching to try this out.
