The GU84B is a medium voltage, high current tube and normally sees 2,2KV. With the high impedance at 4KV you will run into trouble on 10m as t; /archives//html/Amps/2006-01/msg00165.html (10,483 bytes)

Looking now that folks have more info, perhaps its a bit too high. Looking thru sites that list specs on it, I see 2.2-4.25kv lis; /archives//html/Amps/2006-01/msg00208.html (9,318 bytes)

That unit puts approx. 2000 watt. My own Emtron DX4 with 2 x GU84B and 3000 VDCD on the plates (under load) puts out approx. 6000 wa; /archives//html/Amps/2006-01/msg00210.html (10,804 bytes)

It is unusual for a 50 watt resistor to fail in such a manner. If anything they usually go higher in resistance or open up entirely.
