Here is my method to make the small SOIC8 IC mountable on the DIP8 socket.

1. I don't like this part, cutting the perf. board, 4x4 holes. Use acrylic cutter to cut the board, and I use sharpening stone to smoothen the edges.

2. Remove 2 rows of the copper with pen knive. Not difficult.

3. Put all the pins on the DIP8 socket, and mount the board.

4. Bend and cut the pins accordingly.

5. Flatten and bend the four legs on the corners.

6. Clamp the IC and the board with Visegrip, and solder the legs.

7. Done. The Op-Amp with the adaptor removed from the DIP8 socket.

Good work Bram.. This is going to save us some money, instead of getting the browndog.
The volume of my amp goes to 11!!! Does yours?

??? blink.gif ??? Don't understand ???

Do you mean because you don't see the DIP8 socket? It is the final product without the DIP8 socket. The DIP8 socket is just to help to hold the pins. Can be remove when done.

Hi tropical, I bought the pins in a small plastic pack in SLT 3rd floor, the shop at the left side of Kaichin (after the escelator). SGD 1$ for one small pack, which I think enough to make more than 20 adapters. I saw only 2 sizes of pin, I took the small one wink.gif

attempted Bram's method of making the adpator today smile.gif
it was harder then i thought tongue.gif
bought the pins from SLT Sunlight 3th floor, i think the trick is to do the 4 center pins first, then adjust the 4 outer pins.
here's the result laugh.gif the op-amp is a MAX4167 (sample)
Bram, did u use some kind of studio lighting to take your shots? they look really good smile.gif

Sounds like the MAX chip is good for single 9V battery operation!! Wow, that's interesting. Is the power consumption low as well?

Thanks.

There are some (a lot) good BB and AD chips specified for +/- 5 volts, they might be enough for 32 ohm headphone, but not high enough for 600 ohm headphone wink.gif
