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.

I only put the 6SN7 after the 5692 to denote it as a "6SN7 type" of tube. I did not mean to say there are 275 volt tubes that say 6SN7 on them. Yes there are only 275 volt 5692's...Sorry for any confusion. I think you are right that the WGTA should be 450 volt. The W denotes a military version of the GTA (and WGT is a 300 volt military GT). My mistake.
