REASON
During production of the above models, IC201 has been changed for TDA8840,
TDA8843 or TDA8844.  Although these IC’s are similar, it may be necessary to carry
out circuit changes depending upon which type is supplied.  Refer to the ACTION
section below for details on changes.
Note that wherever possible, fit the same IC that was in the receiver originally.
ACTION
51DS02H, 51DS03H, 51DS05H and 51FS51H only:
 
TDA8843 and TDA8844 are completely interchangeable without any circuit
changes.
 
If fitting a TDA8843 with a TDA 8844 remove C402.
 
If fitting a TDA8840 with a TDA8843 add C303, C402, C808 and C809.  Note that
C402, C808 and C809 are zero Ohm resistors.

White – Carry out as required
Yellow – Carry out as required and whenever the unit comes in for service
Red – Carry out on all units
51DS02H, 51DS03H, 51DS05H, 59DS03H, 59DS05H, 66DS03H, 66DS05H,
66ES03H, and 66ES05H:
 
If the TDA8843 is fitted to any of the above receivers, it may be a mask Y or 2Y
(identifiable by 1Y or 2Y being stamped on the top of the IC).  These two mask
versions are not interchangeable unless the circuit is changed.
 
If the 1Y version is fitted, the circuit and parts are as per the service manual.
 
If the 2Y version is fitted, the following circuit and NVM changes have to be made:
1.  Replace R224 with a 270R, 0.12W resistor.
2.  Replace R402 with a 56R, 0.5W resistor.
3.  Replace IC105 with the correct type for the model (see parts list below).
4. Remove T201.
5.  Change the data contained in the NVM as below.
