Hi,
so i was building this power amplifier with a simple pre amp and power supply unit.
unfortunately i thought i did unplug the power cable.one of the input jacks touched the power transistor(2n3055) there is four on the board on a heat sink, with a spark and the speakers started to buzz.I pulled of the power cable.
then I tried to test the amp again there was hissing.after few seconds the hiss was gone but i could smell damage from the board.I touched the big heatsink it was like normal.but when i touch the small heatsink of the BD135 transistor it burned my finger pretty bad.
If I change the transistor every thing will be fine or I destroyed the amp completely?
