Hello Scratchy, I found my kit of the Amp 2 and am having a go at putting it together. Matching the parts to the BOM from the AI is more than a bit difficult - do you have the complete spreadsheet as per your posted photo?

Here you go:
AMP2 - Google Drive
The spreadsheet has multiple tabs. One for calculating resistors based on input values.
Another tab has a spot to tape the SMT tape to each row, with locations for each component. Just print the sheet and stick the SMT tape to each row.
I've also included all the datasheets I could find for this amp.

Thanks very much! My AI is not nearly as comprehensive as yours. Am looking forward to putting all together after quite a few years in "storage".

Same size, better output power (up to 2x42W), lower idle power, and as good if not better SQ.

The TPA3132 chip it is based on is an automotive qualified package shrunk version of the TPA3118.
Put this into a box a while ago. Very efficient but lacks the depth of the Amp 32
