Rather risk doing further damage suggest build a "dim bulb tester", google for plans. It's simply an incandescent bulb in series with the mains supply, it acts as a current limiting device.


Next step would be to diode test transistors in the power amp stage, again google for "how to". Visually inspect the power amp stage for charred/heat stressed components, eg, discoloured resistors, post pix of candidates. Let us know the results.
