Hi guys, just got my e12diy recently and the more I read the more I'm wondering... This "blank PCB" that is supposed to be provided, is it a set of blank PCB adapters just like the given plug and play ones but without chips on it, or is it simply referring to the empty opamp/buffer sockets on the amp's main PCB itself?
From the posts here and manual I interpret it as the former, but my package did not come with any blank adapters. Same goes for my friend's unit. Both of our s/n are early 200s.
Inside the metal box that has all the opamp and buffer, the blank PCB are sitting underneath the foam. Pry the foam out and you'll see them.
