2AP1 Interference suppressor board and main rectifier

Circuit diagram, 2AP1
R7, R8 and R9 are varistors that clip the voltage peaks exceeding about 1100 V. The
varistors do not conduct when the voltage is below 575 V AC RMS, this corresponds to a
peak voltage of 810 V.
Terminal F is not fitted to suppressor boards used in power sources without cooling unit.
From serial no. 039-xxx-xxxx all suppressor boards are supplied with terminal F.
Main rectifier 2BR1 is fitted on the heat sink. See the fitting instruction on page 54.
