3.3. TRANSMITTER TUNINGCAUTION:Do not exceed 450 ~ 475 ma. IP during CWtransmission. Keep tune-up periods as short as possi-ble. Tube life is directly related to the duration oftune-up periods. Make sure the fan is operating at alltimes or the life of the 6LQ6 output tubes will benoticeably shortened.Place the transceiver’s controls in the following typicalsettings for transmit operation.
