Thanks again for all your help, guys. Very much appreciated!
So, I have two issues with testing the buffer chips. A) My meter doesn't have a 'beeper' function, and B) many of the traces on the buffer boards are covered by glue, which I don't want to disturb unless necessary. (See photo) If it matters, while the set is powered up, all ten of the buffer chips' heat sinks get at least measurably warm to the touch.
EDIT: I don't see any connections between the YSUS and Y-buffer boards, other than two small cables. Could the large metal plates I'm seeing between the boards actually be the connectors/conductors?
