For future reference.... 6SN7GT/WGT/WGTA - 300 volt maximum and 3.5 watts per section 5692/6SN7 - 275 volt maximum and 1.75 watts per section.

GT really just specs' the bottle shape so all 6SN7s are GT's in general. (e.g. T-9 Envelope, octal base). Also I think WGTA = GTA = 450V... not sure as I have never pushed them that hard... and not to be nitpicky, but everything on the net lives for ever... so, accuracy is the goal. thanks -Ed (who has way too many 6SN7GT's and needs to unload some soon).
