Details:

The 250TH triode was if I recall correctly, used in industrial and military applications during the 1940's such as the BC 610 transmitter during WWII. Being a transmitting tube with a filament of 5 volts at a whopping 10.

I also used my millimeter to check for any shorts between the other elements and filaments and none were present. Test results filament continuity check passed shorts none cosmetics very nice example of a 250TH with some minor wear to the printing from age and handling. Hi everyone, up for sale is a very nice example of a classic Eimac 250TH triode also designated VT 220 or cv2589.

Despite this setback I was still able to preform a continuity aka beep test with my multi meter on the filament pins and it passed just fine. 5 amps i'm unable to fully test this 250TH even under a reduced load on my Hickok 800.
