If R3 was positioned above the board on its leads, look between the DSP boards and the front
panel board to verify that the leads are not touching any terminals on either the aux DSP or front
panel boards (see Figure 19). If necessary, unplug the DSP board assembly and adjust the
position of R3 to ensure the leads are clear of other solder pads before proceeding.

Replace the three 4-40 1/4” (6.4 mm) zinc pan head screws you removed earlier with a split lock washer
under each screw head (see Figure 11 on page 14).
Replace the knurled nut on the PHONES jack (see Figure 10 on page 14).
Turn the chassis upside down and position the front panel so the pins of P30 and P35 on the bottom of the
RF board just begin to engage the connectors on the lower edge of the front panel assembly as shown in Figure
20). Do not fully mate them yet.
