Has anyone produced a set of *.TUB files for use with the T.A.P program for the popular Russian triodes?GS31,GS35B and GI7B are the three most popular, if anyone has done this I would like a copy, alternatively can anyone help me to produce them. I have read the help file for TUBEDATA.EXE but admit to still being somewhat lost. Regards Conrad G0RUZ
