Application Notes
After shipment or transit the valve must be pre-heated not less than 30 minutes before any anode voltage is applied so that the mercury may be distributed correctly. This rectifier being directly heated it is recommended that the output circuit be returned to the mid-point of the filament transformer secondary.
