Hi Guys
I am rebuilding a digital recorder and am looking to replace the dual op amps with two single op amps on a Brown Dog adapter.

The original op amps were some strange Japanese package that is wider than your typical SOIC.

I find that the SOIC legs on the Brown Dog just barely touch the inside edge of the solder pads on the PCB and I am a little worried that joint integrity might not be so great...?

Can any of you offer suggestons on how I can improve this situation?
Brown Dog does not make this adapter with longer legs!

Thanks and Best

You can make a secondary adapter, a small board that fits the brown dog board and has pins that mate with the original pads. It'll be fiddly, but do-able if you have PCB etch equipment. You might be able to do it with veroboard (perfboard) I can't tell if the spacing is good from the photos.

I'd just solder to the original pads, there's a small overlap, and you should be able to bridge the pins to the pads with solder with the help of surface tension. Again, it'll be awkward, you'll want a solder sucker on hand for repeat attempts, but I don't really foresee any real problems getting a substantial bridge in place on all the pins.

Tack the adapter securely in place by one pin, then do the opposite corner, then the remaining pads. You might get away with bridging all four pins on one side with a big blob of solder and removing the surplus with a sucker. It's a hand skills thing.

Good luck.
