5 new alkaline 9v batteries are *probably* trouble free.

In my 5 x 9v (or 6 x 8.6v NiMH) power supply, the batteries
aged differently, and when one suddenly went to a higher
internal resistance in the middle of a show, my Earthworks
SR-71s started generating ultrasonic noise, and then sonic
noise.  Definitely not trouble free.

But I would like to exercise your guarantee clause, Klas,
and get a clean copy of that show; no one else was recording it.
