2.	Carefully remove the unit's end caps, swinging them out by the rack ears.
3.	Remove five (5) plastic nuts from the jacks on the rear panel.
4.	Hold the front panel, and carefully remove the cover.
5.    To disattach the circuit board from the front panel:
* Pull off the seven (7) knobs on the front  panel
* Remove the seven (7) nuts and washers from the front panel.
* Hold the unit face down, and carefully separate the circuit board assembly from the front panel.
NOTE:	The buttons are loose and can fall out.
* Carefully remove the buttons from the rear of the front panel.

Reassembling the Unit
To reinstall the front panel and circuit board assembly:
1 .   Hold the front panel face down, and reinsert the buttons.
2.	Continue to hold the front panel face down so as not to loosen the buttons.  From the rear, carefully position the circuit board and insert it into the front panel.  Replace the nut and washer on one potentiometer at each end and hand tighten.
3.	Replace the remaining potentiometer nuts and washers.  Check for alignment, then tighten all nuts.  Do not overtighten.
4.	Replace the cover, being careful to align the jacks, and the power connector with the holes in the rear of the cover.

8.  Holding the end caps in place, install the six (6) screws.  Tighten the rear-panel screws which are next to the power connector.

Removal and Installation of Components
From time to time, it may be necessary to replace pots, jacks, the display, or other components.  When desoldering, be careful not to overheat the board, use all caution to prevent damage to the circuit board, traces and pads.

When installing pots, jacks or displays, make sure that they are mechanically flush with the circuit board prior to soldering in place. If not properly aligned, stress can be placed on the new components and the board - resulting in early failure of the board and/or component
