Accessories
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
The BR1608F air cooling requirements are shown on page 5 of the pdf data sheet. 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.
The temperature of the seals and envelope must not exceed 200 °C. Cooling of the seals by low velocity air flow is required.

Notes
- Temporary fluctuations up to + 5% or –10% in filament voltage are permissible.
- The filament current of BR1608F must not exceed 890 A, even momentarily, at any time.
- 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.
- Oscillator output power = P out – P drive where Pout= output power of tube to anode circuit and P drive = drive power fed back to grid circuit.
