cbs	gibson ga-45rvt does anyone know where I can get the schematic for a ga-45rvt? I was thinking about mod/rodding it from 2 discrete channels into a 2 channel switching rhythm/lead a-la TUT, if it isn't a "collector" amp (I don't believe it is), in other words can I get more than ~$300 for it, anyone know? It has a strange PA set up the cathode appears to be fed from a OA2 voltage regulator? also does anyone have any background in the comparison sonically between the 12ax7 and the 6eu7. in the RCA RC-30 tube manual they appear to have the same spec's. thnx , cbs
