Hi, I have a problem with an amplifier, In Phase - Ipa2001D.
I was told that the positive output touched the power ground.
Opening it and checking, I found a transistor A733 short, it changed but it is still in protection.
I now have two situations such as:
If I remove the amplifier TL494 IC illuminates with green LED. But obviously it can not operate without TL494.
If I leave the TL494 but take off the transistor replaced A733, the same LED lights up green, but in both situations I have to remove either one or the other.
I do not understand where the problem lies, than however is due on the power supply, is not it?
I checked all diodes, transistors and final, and everything is ok but, something is wrong.
Tips?
Thank you

Sorry I'm late, but I could not connect first.
The amplifier is still here with me, so I still have some time to be able to repair it.
I think the next week and put it back on the counter, then having the card removed I can continue to ask for help here? Obviously within the limits of the possible.
Thank you. 🙂
