Follow your intuition: just blew out two channels of my Tascam 464 because I didn't.

I just built a nice little battery powered phantom supply, and the url link which I don't have here very clearly said I should check the input resistance of the mic pre's to see if they were DC coupled. They gave 10Kohms as a ball park for DC.
I measured found mine were in that range: 8K. So DC, no wonder they sound good, and it made me remember something from long ago in the manual saying not, repeat, Not to connect a phantom supply directly to the inputs.
So, now you know the story, of course I had the supply on the wrong side of the AC coupling that I had dutifully built.
My INTuition was strongly to actually check the voltages in the jacks and pins first. However of course I was tired, it was the middle of the night, and I just wanted to plug my condenser microphone in. SO I DID. and then I wondered why one channel wasn't working: so then I thought I would try another channel. Then I decided it might be the microphone, so I went else where. But you see the story: two channels now dead: Please at least check out your intuition.
Thanks,
