Removing the Front Panel Assembly: A1, A2, A3, A4, and A5

The front panel assembly consists of the Keyboard (A1), Keyboard Filters (A2),
CRT (A3) Attenuator (A4), and the Input assembly (A5). The entire front-panel
assembly must be removed before any of the sub-assemblies can be removed.

The general procedure is:

1. Remove the Power Supply Cover.
2. Disconnect cable W10 from the Output assembly (A26).
3. Disconnect W3 on the Receiver 1st Mixer (A19).
4. Disconnect W7 from the Front Panel Assembly (A41).
5. Remove the four screws attaching the front frame to the chassis, and move the frame

slightly forward (to provide room to access Motherboard cables).

6. Disconnect W1, W5, W6, MP20, MP21, and MP22 from the Motherboard (A40).
7. Carefully slide the front frame assembly forward until the keyboard cable (W26) can

be disconnected from the chassis bulkhead connector.
