Hi all, getting close to finishing up the build on my BeePre 2 kit but ran into a high voltage reading on at terminal 16 when doing the DC voltage checks outlined at page 55 of the manual. 

Here are my readings: 

Terminal 25 Voltage: 145
Terminal 30 Voltage: 11.8 -> 12
Terminal 06 Voltage: 219
Terminal 16 Voltage: 109.5 -> 110

Here are the previously taken resistance readings as specified on page 53 for reference:

B4 Resistance:450
B1 Resistance: 442
A4 Resistance:440
A1 Resistance: 451

I went through and double checked all connections and component layouts and everything seems in order.  Any ideas on what could be causing this and what I should try next to get the dc voltage where it should be (10 VDC and 100 VDC)?

You are missing the connection at pin 2 of the 4 pin socket.

Don't feel too badly about it, when we wrote the original manual for the BeePre 1, I managed to get the 4 pin socket numbering wrong somehow.  That wasn't particularly fun to fix!

Oh no, what a nightmare!  Well, you all at Bottlehead are awesome, mistakes happen.  This is my third kit, first being the Crack/Speedball and then an Eros 2 - all have been a lot of fun to build and my the manuals are great, I love of all my Bottlehead components! 

Everything is working great now on the BeePre - finished it last night.  Testing now then I will move on to the first upgrade kit!
