HELP Mac MX 130 No volume control or light
My McIntosh MX 130 processor has just had a stroke. I turn it on and there are no volume lights anymore. Worse is that there is no volume. It plays quietly at a single unadjustable volume in all formats. Could it be a fuse? Is it dying on me? I'm searching franticly for the Manual.
