Stupid? I don't necessarily want to comment on that, but here's the diagram from the datasheet:

Pin 1 on it, the top left most pin in the picture, is the output for the first opamp. I am guessing that this would be the point to attach to right?
I don't see anything wrong with your reasoning, but messing around in there making connections, there's always the chance that you'll do some damage. There's the gain consideration too, just so you don't end up with insufficient drive voltage.

Good luck.

Yeah I'm not sure it would be worth it either, though at present I'll likely have to make an attenuator as the output is pretty high.

And sorry bringing "stupid" into the discussion, it is a working and successful product and I don't want to knock them for it . To the relative layperson it seems a strange implementation but there are many considerations, like cost and difference in performance, that they were aware of and I'm clearly not so it was a little judgmental on my part.

The next step will be to try to latch on to the output leg and hope that the output level will be about what I'm looking for. If that fails, I'll have to start a new inquiry into building a quick pad.

Thanks again to all who contributed in the thread, you have been extremely helpful and understanding
