Data Sheet of BR1607F / PET1607F
BR1607F is an air cooled R.F. power triode of coaxial ceramic-metal construction. It is intended primarily for industrial R.F. heating machines.

Accessories of BR1607F
Cathode Connector . . . PA830
For frequencies above 2 MHz, PA830 should be used in conjunction with a strip connection to provide a low inductance cathode return.
Cooling of BR1607F
The required air flow should be delivered through the radiator immediately before and during the application of any voltages. Filament power, anode power and air flow may be removed simultaneously.
Filament and Grid Seals
The temperature of the filament and grid seals must not exceed 200 °C. A flow of air of 15ft³/min (0.43m³/min) directed onto the terminals via a 1-inch (25 mm approx) diameter nozzle from a distance of 6 inches before and during the application of any voltages is usually adequate for limiting the temperature of the seals.

NOTES
1. BR1607F must be operated at the stated filament voltage. Fluctuation in filament voltage must not exceed ±5%. The filament may be switched on at its operating voltage and no surge limiting devices need be incorporated in the filament circuit. The voltage drop in the integral filament leads is less than 1% of the filament voltage.
2. The feedback ratio is defined as Vg(pk)/Va(pk) X 100 where Vg(pk) = peak r.f. grid voltage in volts and Va(pk) = peak r.f. anode voltage in volts.
3. Oscillator output power = output power of tube to anode circuit and P drive = drive power fed back to grid circuit.
