I have a VT-2 tube that came inside a three-dialer neutrodyne. It has a brass base, tipped, spherical bulb with four short pins. Apparently a triode. The base is stamped with "Signal Corps VT-2 Western Electric Co. Inc." along with some patent info. Any test information for this tube? <P>------------------<BR>

Hi Steve<P> You may not want to test this tube? Even dead they sell for $40.00. <P> VT2 is a Western Electric 205A, 1917. It was made as a power amplifier. It can be used for transmitting with 300 plate volts up to 750, similar to a #10 tube but tennis ball shape. There are different varieties. VT-2 type F has a 7.5 volt @ 1.4 amp filamemt, mu 6. VT-2 type G has 9.5 @ 3.4 amp filament, mu 12. <P> The above is from Bernard Magers who worked at Western Electric. <P>------------------<BR>Norm
