I have a old sound card with four devices on circuit board that goes out to attached tiny speaker uses 1aaa battery - from old doll. I must admit im a ele newbie. Anyway the devices on borad R1, R2, 47UF and the TG. What's the 47UF and can I order or what items do I need to replace and program the 47UF? The TG is the switch small 1/4" round with rubber seal around it that contacts the circ board - when press sounds "hello lets play" I would like to reprogram it to say my daughters name "Hello Katie lets play" Can this be done? If someone can help me i could send digital pic of board... thanks.
