Ok just a quick follow-up here..  The circuit does work.  I built the circuit last night and all is well.  This is a good schematic for anyone using 12SR7-GT's. 

I would like to build the Starving Student Amp using the 12SR7GT tube instead of the 19J6.   I revised the schematic to work with the 12SR7GT.   I think it's correct, but am not sure.  Could someone please verify this?  Any help would be appreciated.  Thanks,
