That's awesome, yet another PMB-6 clone then

I didn't read the whole thread, so forgive a dupe question.

That Burwen can is interesting. I lived in the city that made the DBX, and adjacent to the town Burwen lived in, and followed both outfits fairly closely from '75 - '82. I didn't like their products (although liked the logic behind them). I even knew a member of the Burwen family, but never saw or heard about any cans.

They must have been OEM, and must have come after '82. Info?

Hail Bagwell359,
I bought the Burwen PMB-8's new in 1980 from Tech - Hi-Fi in Framingham, Massachusetts for $110.00. I have used them on average for 15 hours a week since 1980 and continue to do so: 40 years of regular usage. They sound glorious still.

Burwen introduced five models onto the marketplace in 1977, PMB-4, PMB-6, PMB-8, PMB-20 and PMB-40. About 20 years ago I asked Dick Burwen about these headphones. He said that he had them made in Germany and modded them into the various models in the states.

Fascinating reading! I was aware of the PMB rebrandings but knew nothing about the man.

Are any of his recordings available?

What would be the best Orthodynamic for 600-800$ CND? (400-600$ USD)

Interesting. I stopped visiting Tech HiFi in 1976 when a sales guy accused me of being some "biter" that owned ADS 810's. In common with this "guy" is we were both very tall... so I missed 'em. Impressed by your loyalty!

I have seen some photo of the box of the Yamaha HP-1, showing that the stiffness of the headband can be adjusted by a screw.Can anyone show any photo of how this works? I'm looking for inspiration for my own design on adjustable headband tension. Thanks

10 years ago, he told me that he had thrown all of his own PMBs away after the ear pads had disintegrated

I throw away my car when the tyres wear out.

I do not know much about Planar drivers but I do have some links to planar drivers from Alibaba that may interest many of you:

https://www.alibaba.com/product-det...pm=a2700.wholesale.deiletai6.4.5a5b5ca9gGBKyg Double-side, N52 NdFeB and size of "95*75*11mm"

https://www.alibaba.com/product-det...m=a2700.7724857.normalList.136.67136c26RB5A6h Has a "Duo-force + single side voice coils design" but I doubt this is dual sided and single sided. It even mentions "single side voice coils design". It also uses N52 magnet and size of "Dia40*H8.5mm"

https://www.alibaba.com/product-det...pm=a2700.7724857.normalList.27.39606c260ncQ5z Single side, N52 magnet and size of "97*76*8.4mm"

https://www.alibaba.com/product-det...spm=a2700.galleryofferlist.0.0.25c1155e4TcLSg Double side, N50 magnet (not N52 which is stronger than N50) and size of "Dia 106*H12 mm"

Hey y'all I was just curious. Between the he400 & the takstar hf580 planar Which driver is better in terms of technicalities, tuneability and also which one would be better in a closed ported cup (yes ik the last one is lil dumb buh eh why not build a closed planar).

 

[rodel808]

Brought out my oldie but still goodie Yamaha YH-1. I think it's time to replace the earpads. Anyone know where to get replacements or alternatives? The pads seems to be glued on. Not too sure but I'm afraid to verify as I might make a tear on it.

Hi, i just recently bought some orthos (specifically the Fostex T20 v2) based on some reviews of them in this site. I expected them to be power hungry and all, so i thought that cranking up the volume on my Behringer umc202hd would pose no problem to them. Boy was I so wrong. They distorted a lot, so much so i thought i got scammed or smth. Anyway, I proceed to open them up and check the drivers. To my surprise the membrane or whatever was fine with no sign of damage. Anyway, i put them together and start playing with the volume dial on them. I found that right around 1 o'clock they reached the maximum volume before distortion (and they weren't so loud for my tastes in chaotic rave electronic music). So my question is...
Are these orthos supposed to work that way? and thanks in advance to anyone who answers this lmoa

It shouldn't be distorting at normal or moderately loud listening volumes.
My only theory is that the Behringer just doesn't have strong enough amplification to power these correctly.
I would first try the headphones with other hardware... amps, AV receivers, etc.... even your phone.
Find a friend with an old 70's - 80's receiver amp... most of those will have enough power.

The only other theory I have is that you're listening to music WAY too loudly. In which case - turn it down and save yourself from hearing damage.

Thanks man, I will try to do that

Hey, guys
Does anyone have in possession 3D model of plastic part that is meant to cover a base of Fostex's T30 righ-left extenders? Spare parts will do too.




Maybe you know someone or have clues who might have what I need. Any help is highly appreciated.
