[MRCA] 1619 tube query

[Meir WF2U]

Jeep,

The 1619 is similar in characteristics to the 6L6, except it has a direct heated cathode, the 2.5 V filament is instant heating.
It's used in applications where battery power needs to be conserved when the equipment is in stand by, the filament heats up and emits the instant power is applied.
