8-pin DIP socket (first mod project)

[Dept_of_Alchemy]

Hi, I'm wondering where I could find some opamp sockets and how much would they cost? It's my first time DIYing, and I just need one...

Thanks for the help! Any advice on how to properly take out an opamp with a soldering iron and some desoldering braid would be appreciated as well.

Use a big blob of solder to heat all of the leads on one side of the op-amp and gently pry it up, repeat for the other side.

A good Op-amp socket will run about $0.60 and as such you may want to grab your local telephone directory and see if there is some place near by that sells them.

Stay away from the Radioshack ones, they are overpriced and mediocre.

If you wanna mod the ENC, removing the opamp is tricky - there are element around. I tried clipping, found no room, and ended up milling all 8 leads with Dremel. Keep in mind that the traces on ENC PCB are easy to pull, so I'll advice against clipping

Would Frys Electronics be a good place to get parts? Also, I'm ordering from Digikey, does anyone have a part number for a 8-pin socket? I searched on the digikey site but being a noob I couldn't find it...

Fry's does carry some machine pin sockets (which is what you want instead of the stamped contact type like ratshack carries)... seemed like when I looked there, it was hard to find some good 8-pin ones though.

A400-ND is my favorite from Digikey, but the ones MisterX listed are good also.

I see... I thought 8-pin sockets were all the same, I guess I had forgotten that I'm in audiophile land.

So what's the difference between the sockets? What physical qualities should be looking for when I'm shopping for one?

Thanks for the replies, and especially for the digikey part numbers.

This isn't an audiophile thing... stamped contact IC sockets are notoriously unreliable. When I worked as a tech in the semiconductor ind. 20 years ago, it seemed like half my job was reseating the ICs in tester boards using these sockets. Using a good socket at that time (like Augat) resulted in much much higher reliability. All the Digikey PNs you were given are machine pin sockets, probably gold plated interior (where the pin sits).
