I found very interesting photos of Victor HP-D70, drivers and pads looks identical to AKAI ASE-50
I'm back. Posted about these here. Apart from the lack of a treble peak, I actually enjoy the sound out of them from my iPhone + (wrong amp for these) Pico Slim. Very relaxing.
The bad news is that at this moment, ludoo's special search engine is finding posts and photos but then pointing you to the wrong locations in HF. Use it with Google in the meantime.
I believe that goo you refer to is factory goo, a medium strength contact cement. In retrospect, it was a cost-effective solution, since unlike a lot of wonder-materials from the '70s, it's held up. But I sure do prefer the arrangement the OEM of the Pro 30 used: a good tight clamp with a rubber gasket. Just pry slooowwly and it'll come off the baffle, but if you're not going to mod the baffle this won't even be necessary.
You might want to consider a strange alternative: using as a host-'phone a model released recently by Audio-Technica which caused us all a momentary burst of hyperexcitement until we realized A-T wasn't making orthos again after all and it was all just a big dirty trick: the ATH-RE70 Retro-Face. I'm not making this up. Looks just like the ATH-2 but the cup vents are dummies and it's a conventional dynamic driver inside. But you can get it in white, and the baffle looks thin, which is what we're after. Not an easy mod if you want to keep the nearly-unique semi-open back of the ATH-2, but at least others have done this transplant (using SFI drivers in the case I'm going to cite) and the modder makes nice noises about the result: http://nihonhut.com/?p=45 I can't be sure the baffle is as thin as it looks in the photo... does this mean I have to go buy an RE70 (REtro, '70s-- get it? >groan< ) to make certain? Argh.. and there must be a more elegant way to open that grille from the inside. Dremel? Drill holes? Hot scriber or awl? Argh.
Ahh, what threw me off was that you were showing driver pics from a different pair of headphones without any goo.
I managed to pry the drivers out for a look. I ended up using some "magic sponge" microfibre cleaning sponge and it seemed to work well enough.
Thought I'd post pix of my mod'ed T50's I call Plastic Pantz.
