3.6.6 Converting a series v board into a service version (until 10.94)
Fig. 3-12 Converting a series v board into a service version (until 10.94)
Procedure
Unsolder SMD resistors (1).
Solder two traditional resistors (2) KN53.0291.080, R = 620Ω.
Solder potentiometer (3) HW11.461, R = 10 KΩ.
Disconnect connectors at positions (4) and (5).
Note
• NO µP version.
• Service version 1318.89.4xx.11 and .89.7xx.11.
• Balancing is done as standard with three SMD resistors (1) that are solde-
red directly to the v board (without laser trimmed plates).
