Anyone knows where to get pins like these? Short, the shaft is thin enough to get through the holes: http://i65.photobucket.com/albums/h226/madcap389/misc/020302a_both.jpg~original Another photo: http://farm4.static.flickr.com/3322/3410025378_f8abdf015a.jpg?v=0 What are these pins called anyways?

I need to build a couple of headphone amps for the micbooth, and I'm looking for a very stable opamp (as in no oscillation, I'm tired of that). Any ideas?

I while back, I had an URL with a company that sold TubeOpamps. Don't recall if it was a kit or ready made. Anyone recall the address?

I've built a cmoy, and the chip was oscillating pretty bad, so I putted a 20ohm resistor at the output. This solved the problem. What I wonder is, if I connect a 32 ohm headphone to the cmoy, wouldn't the 20ohm output resistor be handling a lot of wattage?

If you got 600ohm headphones, does this means that each of the 2 speakers in the headphones are 600ohm each? Or are they 300ohm each?

How do I do that? Where should the + and - of the wallwart go?

Hello. I got 2 nice vu meters, the needletype. I want to make them work. How do I procced?

I looked at ebay and at some onlinestores but haven't found any good source. Digikey: mad expensive shipping. allelectronics: cheap as heck, but doesn't ship to Europe. for example http://www.allelectronics.com/cgi-bi...00K&type=store Are there other stores which ships to Europe cheap?

Anyone?

I had this one in my favorites but when I reinstalled windows I forgot to save them. Can someone please give me the URL?

I've built a Grado RA-1 amp, with the help of the schematic here: http://www.geocities.com/rubin_jpk/r...RADO_schem.gif The problem is, as stated in the title, distortion. Atleast when I plug in a JRC4556 in the ic-socket. When I swap to the OPA2134, everything sounds very nice and clean. The...

What do you gain from that "setup"? As a buffer or what? Doesn't make any sence of it being used as a buffer though, because the opamps are the same.

Hello. My first post here, and it might be in the wrong forum, but I felt like inserting it here, because it is very DIY-related. Well, after looking in the " Post pics of your builds...."-thread, I just went crazy. Where do you guys buy your cases? I don't mean the candyboxes or the homemade...
