You’re welcome! Replacement leads will change your results, but we won’t know by how much until you do it. The large item marked DTU 06n03 is the FET, 06n03 is the part number. Searching around the forum for 06n03 will turn up some results as to whether that’s the “good” East-092 or not, I am not sure which is which with those.
I think you’ve got the “good” one, but none of the East-092 drivers are considered the ultimate DD drivers anymore.
Ah, I see over here - comfychair says that is the good part #: Maybe explanation for not-so-great current output on some EAST-092 drivers?
Anyway if you’re interested in building something that goes even more DD you could take a look at the BLF17DD - BLF17DD Info Thread - Reference.
