Hello everybody, today i want to discuss a certain case i encountered in my work that left me wondering where could the problem be.
I bought an amplifier "The T.amp ta 2400 mkx professional" with a broken right output hoping to fix it, i found the 8 output power transistors of the right side broken along with one of the two drivers "A145" slot to be specific, i replaced the broken Amiercan driver "ca1837" with a chinese alternative "2sa1837", and replaced the output power transistors with new ones, just for the same problem to occur.
Both the new driver and the new output power transistors were broken again.
So i replaced the driver again, and removed the output power transistors complitly, and the amplifier worked properly (the green led lights up and rolly works), but the problem still priciest when i put new ones (power transistors)on.
I tried testing and these are the numbers:
Emiter & base -/+70v
Collectors 0 gnd
These numbers are correct according to the datasheet.
So i ran out of theories and so I'm here to ask you. What could the problem be in this case?
