hello I have a small amp it is called a songtech studio jr. it was made probably in the mid 1980's because thats when I got it with my first guitar from "santa clause" any way it just quite working a few years ago and I've been trying to learn electronics so I figured I'd try to fix it I've almost completely disassmebled it drawing a schematic as I go. My first problem is that when it first quit working a few years ago I took out all the transistors not making notes what a dumb move but I didn't know very much about circuits then and I'm still not to clever but learning it has C1815 and C1815A npn transistors and A1266 pnp transistors and I found the data sheets for these but I'm not sure of the arrangement of them in the circuit when I complete my schematic is it possible to put it on here and maybe someone could help me? My second problem is one ic cx7932 I cannot find any data sheet for it and I don't know the pin arrangement in order to substitute something else. If anyone knows anything about it I sure would appreciate it. Also if anyone has ever seen or heard of one of thes songtech amps or knows where I could find a schematic I would greatly appreciate it. Thanks alot
