The RS282 is an RF transmitting pentode with a 100 Watt anode dissipation.The valve is marked as having an 8 Volt heater and takes 1.6 Amps, the cathode is oxide coated.The anode is connected to the top cap and the cathode and control grid are connected to independent side connections.![](../pics/aad0276a.jpg)
There is an helical inner screen that is connected to the anode.Despite its impressive appearance this Telefunken transmitting triode has lowly ratings. Intended as a Class B RF amplifier, maximum rated RF output is only 110 W at a maximum permissible frequency of 6 MHz. The most interesting thing about it is that it has an indirectly-heated oxide-coated cathode. The anode rating is 1000 V max.The wide glass tube envelope is 55 mm in diameter and, excluding the special base pins, is 240 mm tall.Reference: Data-sheet. Type RS282 was first introduced in 1934.
