Subject: "E" Board Schematic Corrections                       Date: May 29, 1996


Symptom:
 (****)        The "E" Board schematic on page 73 of the Service Manual is
               incorrect. Due to the following errors troubleshooting a shut down
               problem will be difficult. The errors are as follows:

   1.          It does not show the link between IC 903\pin 6 through R852 to
               IC902\pin 7.

   2.          Resistor R853 is not in the circuit.

   3.          Resistor R852 is not connected to IC902\pin 9. It is connected
               between IC903\pin 2 and the -12v line.

               Additional components not shown in the schematic are:

   a.          There is a 47MF\50v (C809) from IC902\pin8 to ground.
               P/N 1-126-967-11.

   b.          There is a 0.001MF\500v capacitor (C813) across D811 (schematic
               location D5). P/N 1-162-318-11


Solution:      Please add these correction to your Service Manual.
