Hi, I have to replace a transformer in a class A single ended amplifier. The transformer currently in there has a labdle that says 115v 0v 115v 0v 50VA "Chinese symbols" 0v 280v 0v 6 3v 0v 6 3v Now I live in the united states, so I don't require a 280v transformer section...

I know this is double posting, but its urgent. Well this morning I woke up to a horrifying smell. I thought it was coming from the street so I closed my window, and yet the smell persisted. So I sprayed down the room with fabreeze and sat down to listen to some music. No music.. That's...

Well this morning I woke up to a horrifying smell. I thought it was coming from the street so I closed my window, and yet the smell persisted. So I sprayed down the room with fabreeze and sat down to listen to some music. No music.. That's odd. So I go over to check if the power switch was on...

Hi, I was just wondering if anyone could confirm that the "military" version of the 5963 red cap was the same as the consumer "audiophile" version. There's only one datasheet, so I'm assuming it's the same design, but are the consumer versions any different? Seems like they have a shinier...

Hi, A while back I posted about needing replacements for a couple different tubes. I have since found a comparable tube to the input's, however I'm still looking for something better than the Shuguang 6P13P Beam Power tube. I've been unable to locate any that have a similar pinout. (top...

Well I picked up two replacement tubes for the 6N8P tubes in the input stage of my amp. Tue original tubes were occasionally static-y and seemed a little harsh for my taste. After studying the data sheet and other data sheets I found that the 6SJ7 tubes could probably fit the bill. It was...

Hi, I'm basically looking for a compatible replacement tube for the 6J8P. I already attempted to use a 6sn7 and it didn't function. Also, I'm wondering if there are any replacements for the 6P13P as this tube is very difficult to find. Thanks. (I realize this may be a double post, I...

Hi, I have a tube amplifier that uses 2x6J8P and 2x6P13P The sound is a bit harsh for my taste and the output tubes seem a little 'analytical'. I want more of the warm tube sound, but I'm not sure where to look. I tried using 6SN7's, however the amplifier output a LOUD buzzing noise.. So I...

Does anyone have any DT-770's that they could pop apart quickly to tell me which is the positive and which is the negative lead? It might be different for each driver... they're marked strangely with a purple marker in mine. I'd REALLY appreciate it. Thanks in advance.

Well I'm paranoid as usual... I recabled my headphones and it all went brilliantly except I took off the wires before marking positive and negative. There was a purple dash on each headphone so I used that as positive. However it was on the opposite side for each, so I'm wondering why that would...

Hi, I've been into audio equipment for a while. I have two Athena towers in my living room and a host of headphones in my bedroom.. But none of the headphones I've tried gave me the impression of a "real" soundstage. It always sounds as if the singer is somewhere up infront of me just a few...

Ok, so I was recently having qualms about the way my DT-770-80's sounded. The mids were synthetic sounding and distant.. (thin) The highs were a little metalic and harsh. The lows of course were powerful. I found myself with some 20 awg solid core silver teflon shielded wire...so I picked up...

tubs=tube *edit* Hi, I recently purchased the amplifier pictured above and was wondering if anyone could ID it (or perhaps the design it's based on) It has two RCA inputs, two headphone outputs (not sure why...) and speaker binding posts. Also, does anyone know if lower impedance...

Hi guys, I've been using a pair of DT-770's for about 6 months now and I enjoy them immensely. They are incredibly fun cans to listen to. However, I have a few qualms. A) They lack a refined sound when listening to piano music / classical. The soundstage is very upfront and instrument...

Hi, I was just wondering if anyone knew the specifics of the beyer woodie mod. I'm speaking specifically about the DT770 mod. Is the plastic cut out and replaced with wood? Or is wood simply glued over the plastic. Also, Does it change the sound signature much, or simply make it look a little...

Ok, I recently opened up my beyer DT-770's to try to fix a crackle, as well as check out the wiring for a project I'm working on. And I'm a bit confused. In between the two posts (L / ground) (R / ground) there's a single strand of something on the order of 50-60 awg wire.. I've never seen...

Hi guys, I've had a pair of DT-770's for quite a while now and recently the drivers (in particular the right, but the left as well) have developed a slight crackle at low frequencies.. or harmonics at higher frequencies.. Or just sometimes in general. I know that I'll probably find out that it's...

Well I got my Beyerdynamic DT770's today. I was immediately impressed by them but the bass did indeed seem to really mask the mids and the highs were a little opressive. However, after applying equalization following the curve below I found them much more condusive to all kinds of music. Luckily...

Hi, I've done some serious modding in the past. However, I've never touched a pair of headphones. I'm interested in recabling / modding a pair of beyers similarly to the way larry does his "Darth Beyer woodies". The recabling is easy enough, but the wooden portion confuses me a bit. Unless...

Hi, I was just looking for a good beyerdynamic DT770 frequency response graph. Title pretty much says it all. I'm interested in trying some equalization once I get mine and just wanted to see what the curve looks like now, so that I have something to base it on.

First I'd like to lay down a little background so that you can perhaps get a better feel before helping me with a reccomendation. I'm a 20 year old college students and I like to do things right the first time around. My first "expensive" piece of audio equipment was a pair of Sony MDR-V600...
