See above.
Try to see about the shorted caps etc, remove the transistors, and do not populate them until you rectify the sub-assemblies situation. Make sure all caps are good, diodes etc. Resistors, of course.
Then you can proceed with the transistors, one-by-one, from the RF X1-X3(see if you could get the voltages more or less within the reasonable distance from those listed), and then to the audio and the audio-power ones, X4-X5, and only then X6.
Do not plug-unplug the speaker while hot. And when working with the X6 in-circuit, it is better if the speaker IS plugged in.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
