LK2 Reliability Modifications
Step 3. Carry out the modification
1. Locate the components as listed in the table below and replace with the values shown (see pictures
below for location of these components). Do this for both channels.
Please note – R49 – depending on what size of part you have purchased, it may be too big for the space
available. If so, the part can be inserted to stand up as shown below.
Please note – R33 is located underneath one of the big capacitors C16 (see picture below). The capacitor
holder must be removed from the board to access the resistor. Turn the board upside down and you will see
that the capacitor holder is held by two nuts/bolts. Remove the two nuts and the capacitor will come away
from the board – but be careful, as it will still be held by a pair of wires. If the nuts/bolts keep spinning instead
of coming loose, insert a medium sized flat-blade screwdriver under the capacitor and press it against the
head of the bolt while turning the nut – this usually provides enough grip to hold the bolt so that the nut
comes free.

R33 20Kohm, 2.5Watt resistor
R49 2.4Kohm, 2.5Watt resistor
C6 68pF 160V Polystyrene capacitor
