I have a few quick questions for you, do you want to keep this amp as close as you can to original or do you mind changing some things ?
I personally would do the following if it was mine.
1: Change the mains cable to one with earth and get rid of that deadly earth switch.
2: The power resistors should be mounted as close to the PCB or power transistors as you can.
3: Remove the power transistors from the side of the chassis and mount a heat-sink inside in front of the fan and mount transistors and resistors there. the airflow will help a lot. The heat-sink should be right on top of the stud sticking up of the floor for best positioning with the fins towards the fan.
4: make the fan variable speed with a speed controller, if it is DC then Joecool85 has a nice little speed control circuit in here somewhere that would work great.
5: make a hole and put a grommet in it so you can mount a large 3 spring tank in the bottom of the cabinet, or mount 2 RCA sockets on the chassis so you can plug the reverb in from outside. (you might need insulated sockets so they don't short out to the chassis.
Its looking great so far.
