Balanced to unbalanced board

[sbelyo]

I'd like to start planning my preamp using these boards.  Does anyone see a problem with using AMB's LCDuino-1 and delta 1 and 2 setup for balanced?

ok, now that I have my locky_z curve tracer working I need to figure out what template to load in the tracer to match the BC556 (PNP) and BC546 (NPN) and what settings to use.  I'm kind of lost in that area and I've never used anything precise like this to match.  I'm pretty sure the unbal/bal boards run at 20Vdc so I'm guessing I want to match for that voltage but other than that?  

Here's the templates available and a screenchot of the settings for one of the PNP templates
