S104 electrical check OK. Two LEDS, one on each side of DIB1
HV board resistors all in place
Phonon twisted pair plugs all done, except one was soldered on the wrong side (pins rather than posts)
Tower thermometer connector replaced. Saw one loose connection, maybe this was causing the instabilities
New connector for the Goldman thermometer. Mount for Goldman thermometer on lid of stack completed.
Made a plan for which tower faces to use, for detector and for accessories (source mover, thermometer)
