Circuit Description—067-0599-00
voltages are developed from the +10 V supply through the
resistor divider string, R313 through R320. Three voltages,
+6.25 V, +2.5V, and +1.25 V are applied to the VERTI-
CAL switch and divided to provide accurate voltages for the
576's vertical sensing circuits. Four voltages, .5V,1V,2V
and 5V are applied to the horizontal to check the base
sense circuit.
Q347 and Q348 amplify the 300 us pulses coming in
from the 576.
