QuoteVga-7 Solved. "blo" battery low. Replacement baterry is a CR2032 (printed on the circuit board adjacent to the button holder). Access is by releasing 6 screws accross top of cabinet and 2 at each side that secure the amp chasis within the cabinet & slide the chasis partially towards the rear to expose access to the battery loaction on the circuit board to the left (viewed from frant of amp). With the amp unplugged from power, found that if new battery is replaced immediately after removal (takes about 5 seconds to clip a new replacement battery in) the amp's settings are retained, & firrmware was not disturbed. For convenience a long shaft insulated screw driver with small 4-5mm blade to partially prise up the battery retaining tab, while using another smaller blade screw driver helps ease the old battry up and then prises it out of the holder - this method assisted working in the confined space available and avoided the need to disconnect speaker leads etc to remove the the chasis from the cabinet entirely to make the change - there is no need to do that. Alls well that ends well, my Vga-7 has its mojo back!!!! Now feeling more relaxed about also servicing the Vga-3 when it eventually also encounters a flat battery. Cheers
