Ok i have a kenwood kac-9102d that is nonworking but i found the problem when i took it to a repair shop. They said that i need transistors, but they want to charge 150 for the repair when i payed that much for the amp.

My question is does anyone know of a diagram or some way i can locate these transistors? My dad assembles these types of circuits for a living but he doesnt know any more than assembling and disassembling.

Any help will be greatly appreciated!

Do you know the part number of the transistors you need? Not the number silk screened on the board, but the actual part number on the transistor itself?

A transistor has a plastic case, sometimes has a metal tab, and 3 legs. It will be mounted to the heatsink via a screw or a metal clamp with a screw, holding the clamp to the heat sink. I know the following picture is NOT of your amp. The amp in this picture has a total of 14 Transistor type items across the top of the picture. There are 6 Transistor like Items across the bottom of the picture. I say Transistor like because they are all not transistors. Some may be rectifiers and regulators. But that is what a transistor looks like.
