Phase
Final Assembly of Model 1254 Receiver
The completed Model 1254 Receiver can indeed be fully aligned
and tested NOW while still in "board form" before adding the
front panel and other hardware. Doing it this way seems
advisable ONLY if you have nagging doubts about a previous
circuit phase test and if you feel the added hardware might
interfere with testing and possible parts replacement in confined
areas, especially near the front panel. However, if all previous
"Progress Tests" have worked well for you, you'll probably prefer
the satisfaction of doing the final checkout of a mostly-
assembled receiver, nearly ready to use -- for real!
If you prefer the conservative approach, perform Step 7-1a, then
perform all Final Alignment instructions in Part 7B. If all goes
well, return to step 7-1b to continue Final Assembly.
7-1a. Plug the Display Board into the Main Board and secure
both the Volume and Clarifier controls to the Display Board with
the flat washers and mounting nuts supplied. Reconnect the
Power Switch and Encoder Cables.
7A: Front Panel and Chassis Installation
Suggestion: Read over all the following panel assembly directions
and see Figures 7.1 and 7.2 BEFORE starting. Also, you may
wish to wrap the outer sides of the font panel with masking
tape to prevent scuffing during further assembly.
7-1b. Lay the front panel face down on a protective cloth,
and notice the 5 support posts for the mounting screws.
Mounting the panel to the display board may be easier if you first
"exercise" the 5 mounting holes in the posts simply by screwing
in and removing a #4 self-tapping ("sheet metal") screw. Do this
for each post.
7-2. Remove any knobs you may have attached to the display
board controls.
7-3. Check all control and switch nuts for normal tightness.
