Next, I turned my attention to the Magic Brain.
The first thing I did was to remove the main dial scale.
I pulled off the dial pointer (it wasn't easy to do).
The dial scale assembly is held in place by a C-clip and a spring washer. Remove these, and the dial scale can be pulled off easily.
I found that the Magic Brain has more rubber-covered wiring than did the main chassis. Unfortunately, this also includes some of the wiring going from under the Magic Brain chassis to the octal plug which plugs into the main chassis.
Question for you people:
The ungrounded heater wire running from the octal plug to inside the Magic Brain chassis is shielded. Knowing that I am going to have to replace the wiring harness to the plug, is it really necessary for that heater wire to be shielded? There is less than 2 inches of cable sticking out from the Magic Brain unit to the octal plug. With the shielded metal tubes and all, I'm thinking it isn't really necessary for that heater lead to be shielded. What say you?
