- 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.
