A Radiotron military spec 807 valve with square brown base, black plates, silver rods, clear top and a sheet getter. THe base is marked AWA ov V2 and 1/4 and DD with war department arrow between. Tested very good. The valve has been tested on the Amplitrex AT1000 and the test results are shown in the photos. Please read the condition section as this forms part of the description. Unpacked weight is 0.070 kg. Note on the gas test reading from the user manual for the tester:In the case of small pre-amp valves anything more the 0.1 milliampere will likely cause problems. With a power tube the interpretation must be different. Power tubes typically show a few milliamperes of gas induced current increase, even if they are good. This is because in these tubes, plate temperatures are generally much higher and there is more surface area on the plate and other tube components which naturally outgas somewhat as it heats up. Also, because these tubes operate with several tens of milliamperes, or even over 100 milliamperes, a few mA of gas current is ok. With power tubes, a gas-induced current increase of less than 10% of normal plate current is ok in most application circuits. For UK Shipping.
