Connection of TBHT negative to HV common removed (R4 in circuit diagram). Labelled and put in MRO bucket.
Anode connection moved to feedthrough J.
Rewired multipin patch panel. Left some grounded (HVC) wires hanging, should probably make this nice later. |

Swapped the old 9pin connectors out and replaced with 2 5-pin connectors, same as on the modules.
See attached for current pin out diagram. Many of the wires are too short to reach the bottom sockets, so wires 2, 8, 9 are not connected in the
connector. 4 spots are empty on connector 2 (right). (6, 7) and (4, 5) are twisted pairs. Unused wires are tapped up out of the way, but we should |
