Remove the two 4-40 screws and nuts from the back panel that hold the zig-
zag shield and the power supply mounting bracket. Try to not let the nuts
get away from you (Figure 10).
Use a 1/16" Allen wrench to remove all the front panel knobs. I like to turn
all the knobs fully counterclockwise before I start. It makes all the set
screws available, and give me a consistent place to re-set all the knobs when
it's time to re-assemble the preamp.
Remove the 3 nuts on the control shafts that hold the front panel in place.
These are typically located on the input selector, balance, and speaker
controls. Remove the front panel
Remove the two 4-40 screws and nuts that fasten the front of the zig-zag
shield to the front panel (Figure 10).
Lift the back panel slightly to clear the lip on the bottom of the chassis.
There is enough slack in the wires to move the back panel back a bit. That
opens up enough room to lift out the zig-zag shield and power supply.
Lift the power supply and zig-zag shield assembly out of the preamp.
