General Electric 211 VT4-C

The 1940s GE VT-4-C tubes in this precisely matched pair are military spec 211 tubes. The white print on the glass has the GE logo and reads "VT-4-C MADE IN U.S.A." with matching date codes (66C4). The flashing on one tube has a cosmetic blemish near the getter (see photo), but otherwise the flashing on both tubes is in excellent condition. These tubes test as new and are precisely matched. At 500V, they test at 110% and 112% for current draw and 117% and 119% for Gm on a laboratory grade Amplitrex AT1000. At 1000V, the tubes test at 58.6 mA and 57.4 mA for current draw on a custom power supply (spec for new tubes = 56.0 mA).
