Changed 100V selection resistor to 0ohm
Added 10k ohm resistor from GNDD to U4 pin 4 (pull-down for MUTE_CTR)
Added 0.47uF / 63V WIMA cap from anode of diode D3 (next to test point T1) to ground
Added 10uF/16V capacitor from "current sense" signal (cathode of D2) to ground
Changed R5 to 24.9k
NOTE: No mods on B3B3XR04
Changed R6, R9, and R10 to flameproof type (matt orange color)
Changed R7 to 221 ohms (RN55D2210)
R201 and R202 = 3.0kohms, 3 Watts (type ERG-3SJ 302)
Changed resistors R104 and R112 to 182 ohms (RN55D1820)
Changed resistors R140 and R141 to 499 ohms (RN60D4990)
Changed resistors R120 and R124 to 40.2kohms (RN60D4022)
Ground pins on both connectors need to be tied together for Trigger and IR to work
properly. Connect pin 13 (or pin 14) of 14-pin connector (To-Front) to pin 9 (or pin 10) of
the 10-pin connector (To-AC).
Change resistor R14 to 50 ohms (irrelevant).
Install ground jumper.
Don't populate (or remove if installed) Q102, R101, and R102.
Install jumper from pin1 of Q101 to pin2 of Q102.
Add a 0.1uF ceramic surface-mount cap across R3 (RS232 protection problem)
Add 1k ohm pull-down resistor from MUTE_VOL to GNDD (between pins 8 and 14 on
connector J401)
Add 10pF mylar capacitors (brown blobs) across R207 and across R426.
Add 10K surface mount resistors from pin5 of U202-B to GNDA_LT and from pin3 of
U301-A to GNDA_RT.
Add ceramic surface mount cap on top of (in parallel with) resistor R141.
Cut trace under caps C140 and C143.
Verify that R113 is code 1002 (stuffing problem on first batch).
Verify that a shield plate was installed under the input board.
R801, R804, R807, R134, R811, R814, R817, R331 changed to 0 ohm resistors
Change R5 to RN55D1001
