Hi, I have a pair of HifiMan HE4XX (Massdrop) which use the 2.5mm connectors on each headphone. These are crap, and cut out if I move my head the wrong way, etc., so I was toying with replacing them with something better. I was wondering what other connector types people use and how they like...

Anyone know of a mini connector that will fit these to replace the locking right-angle connector on the headphone itself? I replaced the HP connector on mine with a Neutrik as the stock connector did not fit my extension cable very well. I noticed that these use very small enameled conductors in...

Anyone have the specs for the charger (including center + or -)? I'm troubleshooting a users amp and they didn't send the charger (battery is discharged). I'm guessing 18-24V, center +, but need to determine this for sure. EDIT: nm... charger was in the box and some dumba$$ forgot to look...

I have built the boards for this project (Aleph P1.7 preamp). I really like what this user used for cases, but am not sure which ones they are. Any guesses? The preamp PCBs are 110mm x 81mm, and I would guess that the larger case is standard preamp width (17-19 inches). I will measure...

Not my sale, but there is one in the FS section right now: http://www.head-fi.org/forums/f44/fs...ii-amp-329991/ Seems like a number of people were looking for these not too long ago...

Just read this on another forum today: Gorgeous enclosures for DIY amps etc - pink fish media I've never used these guys (yet); but had intended to at some point... hope it isn't true...

Hi, I obviously haven't researched this enough, but want to solicit opinions anyhow, as many head-fiers seem to be knowledgeable about this kinda stuff. My soon to be 13 year old wants to start doing some recording, as well as possily playing with a band he is in. He is asking for mics...

Got an email today with this as one of the items: http://www.mcmelectronics.com/produc...me=MCMProducts Use source code EMC013 to get the special pricing ($10), valid until 10/17/2007 Edit: I use a Hakko 936, and have never used or seen this unit... the price looked good though

Stupid question (probably), but I was adding a relay to an I/V stage I am building. I have +/-15V supplies available in the player. The I/V stage itself will have its own +/- 15V supplies. I figured it would be better to not run the relay from these, but use a +15V from the player instead for...

I'm currently building a test board of cetoole's I/V stage, and had tacked on this PSU/regulation section from rbroer's less simple I/V stage for a TDA1541a. I thought I had things to a manageable point with the I/V stage until I made the fatal error of putting my scope on it Here is the...

Hi all, I was using an Eagle library (tubes.lbr) that I am not sure where I got. At any rate, I had a PSU board made up for my preamp with a 9-pin Noval socket on it. Upon getting the board and looking at a socket, the pin circle on the socket looks considerably larger than the Eagle part...

Anyone have a copy of the d-33 service manual they would be willing to share? Thanks, Chris

Hi all, I currently use a PCDP into a Gilmore amp at work, and am looking for a new one. It must have a line out and a wallwart powering option. I don't want to use my work computer for audio, so that isn't an option. Any recommendations for a PCDP to replace the Sony D-E307K that has begun...

Hi all, Tried doing a search, but... My wife likes to watch TV before she falls asleep, so I am looking for a somewhat smaller TV (maybe up to 20 inches or so). Any recomendations? I would like something <$300 or so, and would still consider CRT (Sony WEGA or something)? However, an LCD or...

Hi, I already did a search of the forums (as well as any other forum I frequent), but I still have a question regarding the DEQ. I just got one of thes, along with the ECM8000 mic, and was going to use this for room correction between the preamp (Counterpoint SA5.1) and the power amp (Odyssey...

Cheaper the better actually. I am switching locations at work into an area that is really quiet, and need to get some closed phones. I've read some of the threads, but didn't come to a clear conclusion. I have a DIY Dynalo which I use only at work, so amp requirement isn't a problem. I think I...

Well, ya gotta be a sick DIYer to equate the subject line with the real post subject, but... I have been harboring some reworks/design enhancements for some of the PCBs I have used (home etched), so I've been waiting to give it a go and get a few boards done commercially. SInce I had several...

Looking for some Sanyo OSCONs from a supplier in the US. I know Partsconnexion has 3 or 4 types. BDent supposedly handles them but doesn't seem to have any in stock that I could find. I'm looking for some 10uf 16V (min) and some 47-56uf 25V (35V better, SC series). Anyone? Chris

My son got his built (I'm fixing it; actually he did a good job, but somehow I wound up blowing the ground opamp up). Using LM6172s in it and after replacing the ground opamp, I noticed that it is distorting when you turn it up to any reasonable listening volume (as in being able to hear it)...

Potentially stupid question alert... I am building an Aleph P1.7 preamp and had a question regarding transformers. The PSUs are dual mono (1 for each channel) and are identical, requiring an input of ~56-60Vac. Can I wire these from the same secondary in parallel or do I need to use either...

Per title, anyone manage this? Just finished one of my Pint boards for one of my sons tonite (actually, he built it), and was going to order a couple of Hammond C801 cases. I've been searching the builds section, etc. but haven't seen one in the little Hammond case yet. Chris Oops...

I still have a couple of Pint boards to build up and was looking around for the mini3 BOM or info and didn't find it yet. Any of you have a BOM or something (I saw a reference to a .pdf file, but couldn't find it). Thanks, Chris

What is the current concesus on what is good or what to avoid in these? Was going to place an order with Thomas Distributing today... Thanks, Chris

Hi all, Not exactly headphone related, but thought I'd share what I've been up to with my Counterpoint SA5.1 preamp. I'd been having some trouble with noise (hum, etc.) ever since I got this thing about 5 years ago, and have slowly been modding it (Elna Cerafines, etc.) and had made some...

As in title, I'm looking for some mini coax, must be 75 ohm... from what I can see something like RG187? Having trouble finding anything available by the foot and was looking for recommendations. Thanks, Chris
