Cooling
The centrifugal blowers provide the necessary cooling of the amplifier, even during long contests. The
main blower is activated by switching the PA on and it is turned off when after-cooling is finished
(approx. 1-5 min after switching off the PA depending on the temperature of the tube). The
supplemental fan is turned on depending on the temperature of the air exiting from the amplifier. It is
switched on at 70°C and switched off at 60°C.
