Change op-amp in BT928

[Sarethi]

Hi.

I'm gonna install an IC socket, at least that's what I think they're called, so i don't have to solder whenever I change op-amp. Now my problem is I don't know exactly what socket I shall use or what they're called. The op-amp that's soldered into the board is called NE5532 with total of 8 pins (4 on each side). I think these type of op-amps are called "double". I also have read that there are 2 different kinds of mounting on the op-amps, surface mount which I guess is what you use with a socket and hole mount which is the type that you solder into the board. So I guess I won't be able to use the NE5532 in a socket since it's the hole mount, so i will just have to buy a new one that's for surface mount?

Thanks for any help.

surface mount are chips that look like this . you can't socket surface mount chips.

thru hole chips have their leg's sticcking out the other side of the board to the chip itself. they're the ones you can socket.

you want 8pin dip sockets if you have thru hole mounts for your op amps

Hi Sarethi,

Welcome to Head-Fi!

The socket you are looking for is known as a turned pin DIL socket look here you want an 8 pin DIL socket.

The NE5532 is a dual chip and comes in a PDIP package (8 pins) The DIL socket accepts PDIP chips so you don't have to worry about surface mount etc.

Good opamps to roll into the B-Tech 928 (into your DIL 8 pin socket) include OPA2227, OPA2132, OPA2134 and AD-843.

I replaced the 5532 in my 928 a while ago and IIRC the OPA2132 sounded a lot better than the 5532 in this application... It's a direct roll in replacement and will work without any modification to your 928.

I wrote up some blurb on it here

2132 on board

Hope this helps.

Pinkie.

Thanks for the help guys. And thanks for the welcome.

PinkFloyd, does the DIL socket have to be "turned"? This one from the same site would it work? The reason i'm asking is because I can't find a turned 8pin socket in the biggest electronic store in Sweden Elfa they only have 6,22,24,32,64 pins. Although they have unturned one's. Thanks for any help!
