Shoot... While probing around I shorted pin 7 to 8 of the pom board. Now I've gotta start from scratch. I'm going to get some sleep for now. Been working all night.
Alright fellas so I found that when my probe slipped it shorted an output transistor. I'm all out of IRF540s so I have to wait on them. In checking the resistors I found that the source resistors R18 and R19 are reading open/high resistance instead of .1 ohm. This is not on the bank of the transistor that just shorted out. Could it be what was causing my missing top half of the waveform?
If the resistance was too high (open), it effectively disconnected the top-side FETs from the speaker terminals.
