Tea,

Here is what you do, take a wire cutter and clip the leads of the old cap off. Remove cap and put in trash. Trust me it now thinks it is a resistor due to old age! Take new poly cap and run leads through board and attach to connecting pin by wraping and solder. Move on to next cap and continue. The original design does not use bypass caps, do not screw up the sound by hearsay engineering. Trust Sydney Corderman on the engineering side, his designs tend to have high resale.
The power supply caps are FP twist lock type and see my previous post for sources. Remove the old ones paying attention how everthing is connected and install the new ones the same way. If you wire them wrong they may explode on turn on so make sure of your work and/or wear safety glasses!
If you replace all of the caps your noise will decrease along with the distortion and the amp will play loud and clear.
Yes, the original transformers could have a concave shape to the sides. That is the original shape on some of the ones I have seen. The transformer can be dented as the can is only aluminum so it is somewhat soft. The way to tell if the transformer is good is to replace the defective power supply caps and measure the voltages. If the voltages are correct the tranny is fine.
