Yep, sounds like the AC LO and DC LO signals from the 2 VAXen are being
linked through the BA11. Try removing the thin yellow and purple wires
that link the backplanes to the BA11's power supply (they go to the small
6 pin connectors on the distribution plate). In fact, if you're not using
the Line time Clock (LTC) signal, (and almost nothing in vaxen does), just
unplug the 6 pin connectors all together.
