Would this work in the PINT? ebay link Too many for my needs but I think someone could get this for a decent price. The prices for comparable wimas at mouser are too expensive.

Where do you guys buy FR4 copper clad boards?

Since the PPA and PIMETA was primarily designed for use without input capacitors has anyone experienced problem with dc yet?

I've tried sharpie and various other brands but none gives me the results that I want (especially thin traces). I've tried layering lines with the sharpie but hazing/spotting still occurs after etching. Small letters are non-existant and ends up to be little specks. I use a small glass dish with...

Just noticed today that the el2001 and meta42 board was taken off tangents site.

Hopefully it refills itself every week or so.

I see the same questions over and over again on most forums. Typical questions on head-fi is "Whats the best headphones under $xx" or other variants of it. Kind of annoying to fire up my browser and see this regurgitated crap over and over. Having a bad day...don't mind me.

I have a few members in my family with lifelong injuries and the fees for medical supplies and such became ridiculous to the point where my quality of life consists of internet and my existing gear. I can use a break and someone mentioned to apply for one of those healthcare plans. Does...

I want to make it so that if a headphone plug is inserted an LED light turns on indicating it. Is there an easy way to do this? Also, how do momentary switches/buttons work? I saw some very nice buttons but they are all momentary and would like to configure it for use with an amp's power on/off...

link Anyone have any info on these?

Does anyone with a turtlebeach santa cruz know the opamp(s) that is used on the board? Would the AD8620 work or are the pinouts different? I was looking at the card and it seems there are 2 soic type chips on it. Using magnifying glasses I still couldn't identify the chips. Thanks.

I like how the hammond aluminum cases look but it is too fat for my tastes. Is there anything similiar to the design but a bit shorter? Perhaps 1-1.5 inches tall. The size of the Audio Alchemy headphone amps would be perfect. I tried to look for some but most images weren't too clear or I...

When I lower the gain on my amps why does the bass disappear along with it? The difference is pretty dramatic to me. Unless I set the gain higher than my listening comfort level, lowering it to match for example grado's kills the bass and virtually makes everything sound "flat". Is there anyway...

I made a cha47 variant and it has problems when I use 2 opamps with it. However, it works perfectly fine with only one in either socket. My first thought was that it could be faulty opamps but I ruled that out by testing. My second hypothesis is that the 12v wallwart may not be enough. I would...

I was wondering if there was an opamp that would work in an amp with only 1.5v such as from an AA battery.

When I go into a fastfood place and buy a burger, it looks old and slapped on together. It looks nothing like the juicy fresh thing they advertise on t.v. Why is that? It's like watching a car commercial for a new car and finding out at the dealer that it's rusted and has a few dents. Am I...

I was wondering if you can use a cmoy as a microphone preamp for recording with an MD player. If so, what gain would be appropriate?

The left driver is very noticably weaker than the right side. Did this ever happen to anyone else?

What would happen if one stacked opamps?

I am looking for some headphones that has the same characteristics as Grado(slam) but with a airier larger soundstage. Does anything that resembles this exist? I was thinking about the AKG K501 but most reviews seems to point out that the sound is very tame.

The 2 100uf 16v capacitors next to the versajack. I changed them to 2 470uf 35v and they fit perfectly without any special mounting. The first thing I noticed was the increased bass and less distortion at high volumes. Anyone else try this on their soundcards?

Anyone planning on getting ex51/71's and comparing them to the ex70's? ex51 ex71

What modifications if any, can be done to an inexpensive amp such as the cmoy for it to be able to drive small desktop speakers?

I noticed the majority of soundcards have tiny 100-220uf caps on them. Would changing them to larger values be beneficial to the sound?
