I’m going through the boards of my NAC 72 identifying which are which:
- The single board at top-left is an NA 325/7.
- The pair at top-right (in front of the phono sockets, but not phono boards) are a pair of NA 324/7.
- The pair lower mid/right are NA 729/1.
- The pair lower left are NA 321/5.
Next I’ll go back to the prev referenced sub-boards discussion chat and see if I can build on what these various boards are, what they do. Ultimately I’m working towards getting an answer on what will work best for me. a) Use the Denon TTs built in pre-amp and get ‘pass-through’ boards for the '72. Or b) switch off the TTs inbuilt pre-amp and try and find a pair of phono boards for the 72.
