Stealth analog? Right. Maybe as a patcher with a D-6.
When I got my D-5Pro that was stealth. The Nak550 and the Teac PC-10 I used before that not only used boxcars of D cells and were the size of big city phone books they had no phantom power. So... in addition to sneaking in the machine, the blank tapes, the extra batteries, cords, mics, shotguns and a mic stand you had to add some pre-amps to the mix.
Even at dead shows where taping was allowed when you were in, you still had to sneak the gear past security. I used to be really good at subtly twisting my body during the pat down to keep hands away from whereever the hardware was. We would split up the gear among several friends and go in separately because once they found batteries, cables, mics or anything else you could count on your whole bag being dumped out and a thorough frisking that would find pretty much anything you had.
In addition to having several people carry stuff in, we would have extra friends waiting to see if you got in. If you did not, you would hand off the gear out of sight of security so they could give it a run as you would get checked very well when you came back in.
We also carried extra blank tapes. If you saw security taking tapes from people you would swap out blanks for the show so far. Somehow those knucklheads never caught on to that one.
Sorry for resurecting such an old post, but the topic was nostalgic.....
