Date: Thu, 27 Dec 2001 05:52:28 -0800 (PST) I observed two things about the whistle: it is also present with the volume all the way down and it does cease when the HD spins up in my newish (used to be heehee) unit. I haven't looked at the schematics yet but it could be that one of the voltage inverters (there must be several!) that feeds the HD goes into a sort of "burst" mode which is about 1 kHz (that irritating whistle) and goes to an ultrasonic frequency when the HD draws current. It's likely to be a messy mod in any case! T.J. . . . . . __________________________________________________ Do You Yahoo!?
