Data Sheet of BW1606J2f / PET1606J2F
BW1606J2F is a water cooled power triodes of coaxial ceramic-metal construction. It is intended primarily for industrial R.F. heating machines. It comes with an integral water jacket.

Mechanical Characteristics of BW1606J2F
Overall dimensions . See outline drawing
Net weight: . . 3.3 kg approx
Mounting position . Vertical, either way up
Accessories
Water coupling supplied with BW1606J2F PA323A
Thermal fuse, available for BW1606J2F . PA85E
Cathode Connector . . . . PA830
For frequencies above 2MHz, PA830 should be used in conjunction with a strip connection to provide a low inductance cathode return.
Cooling
BW1606J2F has an integral water jacket. Minimum water cooling requirements are shown on page 7 higher rates of flow should be used where possible. The water pressure in the jacket must not exceed 6 atmospheres.
A thermal fuse, part number PA85E (melting point 103 ⁰C), is available for BW1606J2F to give protection against anode overheating. Two fuses should be used for maximum protection, screwed into the holes indicated on the anode mounting plate (see page 8). The fuses should be connected by a non-conducting cord to a suitable switching device; a tension of about 1 pound (450 g) should be applied to the fuses via the cord. If the temperature exceeds the safe limit, one or both fuses will release and the fuse cord is pulled outwards; this should actuate the switching device and remove all electrical supplies to the tube. Replacement fuses can be supplied to order.
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. BW1606J2F 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.
