Figure 11. Closeup o f Main Transformer and Tube Power Supply Chassis
while all other tubes on the chassis are vacuum
tubes of the type indicated. All other components
in the power supply circuit are mounted under-
neath the chassis.
Figure
12
shows schematically the location of
the brush assemblies, die and stripper assembly, and
the card levers. The hopper card lever is located
directly under the hopper. The punch brush 1
and die card levers are mounted
oh
the front side
frame. T h e former is located directly under the
punch brush
I
con,tact roll while the latter is
located under the second set of feed rolls. The
punch brush 2 card lever is mounted directly
above the punch brush 2 contact roll.
However,
all card lever contacts are mounted on a plate at
the front of the machine as shown in Figure 7.
Note from Figures 13, 14 and 1 5 that there are
no relays in the electronic unit.
Figure
15
shows
the gates open with all connections accessible. The
general function of each tube chassis is given, but
no effort will be made to discuss these further un-
til the section on Electrical Principles. T h e switch
and push buttons shown in Figure 1 5 are not ac-
cessible unless the large gate is open; rhey are in-
tended solely as an aid in servicing the unit. The
blowers shown are provided to cool the tubes. Over
1200
watts of heat from the filaments alone must
be dissipated.
One blower is provided for each
side of the electronic unit.
