Actually, in theory identical resonators should be balanced so there 
should be no nett voltage at the base. In my case, the L/C ratio of 
the resonators is slightly different despite identical tuning. I will 
wind another so I get the two identical and check again for base 
voltage wrt ground. It is more than likely also that the link 
coupling to just one of them is causing an impedance disparity. It 
might not be possible to null out the imbalance under these 
conditions as the loading conditions are different for the two 
resonators (and of course, highly variable).
