How to repair my double cassette recorder?

I have a Kenwood double cassette recorder model number is 6050 and it is dead, won't switch on , no lights and nothing works. There is no fuse inside to blow out. 3 electrolytic condensers have leaked their fluids. One of the power transistors has come loose from the soldering. When switched on, some burning or heat smell emenates from the circuit board area near the front. This may be normal. But nothing works!!!
