Adding R30 if your PCB doesn't have a place for it

Only perform the operations in this section if your PAT-4 is one of the early production
models that did not have a place on the PCB for R30.
Insert a 48K7 Ohm resistor into the back of the board as shown in Figure 5. Note that two
leads fit in the one hole that connects to eyelet 5: C4's still unsoldered lead, and R30.

Figure 5-Insert R30 in from the back of the board

Solder both sides of R30. On the Eyelet 5 side, you'll solder C4 and R30 leads
simultaneously. Clip the extra lead length on both sides of the board.

Installing the DRD4 Kit

If you purchased a DRD4 Kit, this is the perfect time to install it. See the DRD4 manual
for details. The special DRD4 transistor and heat sink replaces the stock transistor Q4 and
its star-shaped heat sink.

PAT-4 PWR Modifications (Optional)

The modification in this section must be performed only if you chose to install the 1650
Ohm resistor for R6. That change doubles the output current available from the phono
