Have re-installed the +10V and -10V. Regulated
Power Supply in the Kluge Bay after 2 diodes
and 1 transistor was replaced. Note: The white wire
of the red/white pri going in to the supply is
the 115VAC hot line. The supply is working now.

1240 Earl has replaced the 15 amp toggle switch
in the QI Control Unit. He also corrected the
interchange incoming AC power lines so that the hot
line - not the common is switched.

Last Friday Ted tested all of the tubes
in our two TV monitors. The 1G3 in the 19" monitor
(which is the one normally used) had a heater to cathode
short. It is believed that this is what was causing
the dark bands to sometimes appear on the monitor.
The Monitor system still needs to be worked on
because other dark bands are on the screen. This
means that 60 is being picked up on the
video circuit.
