Make sure your getting a square wave to the outputs. Check the gate drive transformers and the LM5110 drivers.
LM6172 for carriers and other functions.
T40001bd LM5110 for gate drive.
T30001bd
T20001bd
T10001bd..........all use UC3706DW for gate drive.
Does anyone have a gate drive transformer for this amp i can buy ?
T401is defective on this amp and need a replacement ..
Anyone know where i can buy one ?

it is really difficult that these transformers are defective.
How can you say that these transformers are defective?
what kind of tests you have done?
The transformer is defective someone pulled it from the board and pulled half the windings off and glued it back to the board ..
So yes it's defective
So yes it's defective
uhm, THESE occasional large radio technicians!
In fact it was weird! unless someone do not fire them, those transformers are hardly bad. And in this case, someone pulled them away by force (him on fire! Haha).
I'm sorry for your situation, but I do not know how to help you in this case.
