After further review both of your pictures are equivalent! The wide heat sink pin is connected to pin 2....
I am getting a used NR1501 in a few days.
Pinout from the schematic:
In twowheelin's picture it initially looks like pin 1 and pin 3 are shorted via the pin 3 board trace... I think after understanding that the heat sink is also pin 2 there must be an insulator under the pin3 board trace in his picture.
On a side note:
I the NR1501 used and cheap so I plan on also modifying it to replace the composite video I/O with peouts for all of the channels. That way I have a small slimline 7.1 decoder that I can link to my larger atmos receiver.... The project will be tested over the next few weeks.
