This is probably just me being an idiot but I have been staring at my BeePre and checking the manual resistance values for A2, A3 and B2, B3 and they appear to be the opposite way round... The check in the manual says A2 and B2 vary with the volume / balance 0 to 50 yet I do not have either connected to the Volume control. In fact I have A3 B3 connected to the volume... and the values I am getting in the resistance check would fit if A2 / A3 were swapped and B2 / B3 were swapped...

My A2 is 272 and my A3 is 16.6 with my B2 at 272 and my B3 at 16.15...

Any thoughts or have I just spent too long staring at circuits today...

Yes, what happened was that we had them switched in the original manual, then fixed them fairly immediately thereafter.  Somebody who bought one of those first run kits ended up waiting a long time to build their BeePre, then posted about the mixup, and we accidentally switched them again.

A2/B2 will have the 100K+ Ohm resistance reading, and around 100V DC.
A3/B3 will have 0-50K Ohm resistance reading, and 0V DC.
