Orthodynamic Roundup - Page 792

damn..taht is a great find there

8 ohm impedance eh..you can use an amp to power it straight ..awesome!

hope you get the faulty driver issue sorted out

yup, i hope so...i check it using multimeter both of the driver seems to be just fine, but there's no sound comes out from the other one...the other just normal & sound potentially...

Cool find, iQEM. Looks like Fostex weren't the only ones sharing their drivers.

ericj or whoever else has one, could you measure the space for the drivers inside the enclosures of your QP55x? I'm considering using one as a donor frame but need to know if my drivers will fit.

That's one unexpected find of an ortho driver in a strange enclosure. Perhaps that volume control (?) (or is it an eq?) thing is what's faulty?

I hope you can get it playing

Amazing find, congrats iqem!! i wouldnt never have thought it was an ortho, with all those knobs on it.

Do you think this is an ortho?

The VSH-5 Vector scan is in the ortho list... but I have no idea how it appeared in it.

Pretty sure it's because someone here bought one - it's an ATH-2 with a different label iirc.

ath-2 has arrived.
i got this cheap enough that i am going to full-on mod it. point me to any ath-2 succesful mods plz!

The most important thing to do to the ath-2 is to cut the front grille open and let the driver breathe.

Those little holes are doing it no favors.

any pics of these mods to help guide me? i'm pretty sure what to do on the front but not the back.
the treble on these is terrible, bass is decent, tho not as good as the pro 30

Tried the ath-2 with my xenos amp. much better! turns out the ld3 has little synergy with this old ortho. the highs are still recessed but the whole headphone came alive with the xenos amp

yup, it's very identical with Yamaha YH50A driver...

i dont know, my friend had spotted it on local antiques store...i guess he bought it for the branding reason, later i know it's an ortho from his pict on my local forum...he didn't know what to do with it, so i bought it from him...

yup, they hot glue the driver to the baffles...the circuit are for volume controller, treble & bass booster on each cup...and extra Mono-Stereo switch on the left cup...i dont know if it's work or not, too many cables inside...so i bypass the circuit, from cable directly to driver...

i think so, haven't test the circuity yet...well i dont have any interest with it at all...

same as you do, but after seeing the drivers i'm very excited found a missing ortho from Sony...

and yes, i think so about the VSH5...let's figure out, shall we ?

you mean the one without strap leather ? if it's true than you're the one who been outbid me ? sorry if wrong person...

for ATH-2 i put some nippon tapes (covering 3 holes) on the driver, covering 2 holes on inside of the baffles (near driver)...and lining the lining gap on baffles (open the earpads to see what i've meant) with nippon tapes...for the driver, maybe using 3M micropore surgical tape would bring more treble better than nippon tape...
