SOIC to DIP bodging

in

Have you tried to contact Mackie directly? I have found them to be extrememly helpful when looking for parts. See the link below for contact info in the UK:

If you take any old scrap SOIC and .5mm grinding disc in a Dremmel you can slice about 1 to 2 mm into the long sides and the remnant PPO and pins stay in place sufficiently to solder wires to the exposed interior fingers. This retains the SUIC spacing for pcb soldering. Relieve back the PPO about half mm with the grinder , on one face to make some lands. Assuming enough physical space for the DIP to wire to the 2 half "SOIC" strips.

Thanks Dan, but they do not supply at component level, though they could sell me a whole PCB .......

Found this on google. US company.

Look at some of the DIP -> SOIC adapters available from . They go in the wrong direction, so you would need to get creative but there may be something that could be adapted.

Alternately, the simplest approach may be to just dead-bug the DIP upside-down in a convenient place on the PCB and run tag wires from the DIP pins to the SOIC pads.

Correction, DIP pins wired to hard component points that nodal-map to the SOIC lands

Stock exists in Sydney and in Farnell's Asian warehouse.

Thanks, thats the chip, but Farnell UK will not get me these from Oz or anywhere else other than Liege Belgium. Something about their distribution centres being independent - sounds bollocks, probably just costs them too much to bother..

I spoke to an obsolete device supplier today who said there are remarkably few of these things around, and that the Americans have issued some sort of control directive over their distribution - something to do with promising, if you buy them, you will not sell them to terrorists. (Maybe Al Qaeda have ben found using Mackies to broadcast call to prayers).

Interesting how Mackie use this device both as a compressor and a high pass filter. Not seen that kind of thing before. All 4 outs are DC, so the whole preamp is well f**ked up.

Blimey, thanks for that Steve, will definitely take note.

Gareth.

Thats certainly the solution, now to try and find that in the UK!

Cheers,

Gareth.
