I have the following system (Garrard A70 Turntable, JBL D-130A Woofers, JBL 175-DLH HF Drivers, JBL N-1200 Networks, McIntosh C-11 Preamp, MC-240 Power Amp and MR-67 FM Tuner). Everything worked GREAT in 1997 when I put the system in a closet for storage. When I put everything back together last week, there is no sound. The tubes glow but the tuner does not make a noise and the turntable doesn't turn. I love this old system. How can I begin to troubleshoot and repair it? I am a novice, so no big words please. Thanks, BobTexas.
