Olimex has improved since I last used them. The component printing looks better. They are using immersion gold as the old plating was not RoHS. Minimum width for component printing is now 5mils. Trace/Space is still 8 or 10 mils and the drill rack policy is unchanged. You can see how...

I've got one MAT04FS and two SSM2210S. Yes those are in SOIC packages. Date codes are 0104 and 0331 so I've had these for awhile. I think I bought them directly from AD along with a few MAT02's. These are free to the first person that replies to this thread, correctly identifies what these...

I just bought a Edsyn 1032 on eBay for $45.00. It looks like it is missing the sponge holder.

Has anyone tried using an LM317 as an audio amplifier? I've seen several schematics but never an actual device. National has a couple of schematics in the LM317 data sheet where the 317 is a current source and a LM195 or LM395 for an output transistor. I like the idea. The resulting...

I'm looking for recomendations for an inexpensive low-volume PCB manufacurer.

Has anyone had trouble ordering from Stereoheadphones.net lately? I ordered a pair of HD-580s last Tuesday and haven't heard anything from them since. They haven't charged my card, they haven't responded to my emails and when I try calling them I get this message: "The mail box for 'Apex...
