Hi. I have the same board! That is a 10uF 25V tantalum capacitor. I have the same board, but a different problem! I have a burnt out resistor. If you could check its value for me, I'd be very grateful. It's the one right in front of a Motorola MJE1090 transistor, which is the one with the tallest heatsink next to a large 4 Ohm resistor. Thank you.
