Confirming hardware revision for EMUBlack resistor

Hey, I’ve heard various things about the HW revision for the EMUBlack to include the 150k ohm resistor internally.

On the EMU Classic its revision O, but I’ve been told it’s a different revision on the black. I’ve looked through all the documentation I can find but haven’t found an answer yet, anyone know the answer to this before I splice my stock wiring loom?

Thanks in advance!

It´s suggested only with LSU4.9. All HW versions.
