Interwinding capacitance of both secondary windings of mains transformer of several 100pF looks like a short circuit for high frequency digital noise, which makes both ground planes being connected again by two paths. In a Sub pico farad bridge I built recently, which would NOT balance, I placed a grounded shield within the transformer and stopped interwinding effects dead. Not saying he should do it, just that there are benefits to screens. Steve |
