7591s are currently being produced at Saratov, Russia (EH) and Jamona, Slovakia (JJ).Of late, JJ has been having QC problems in Octal tubes. So, EH is, at least for now, the primary recommendation. The EH tube's "bottle" is larger than that of NOS. If things are really tight, space wise, you may have to use JJ.
Unlike NOS, current production 7591s are not forgiving of grid leak resistors that exceed the max. allowable value. So, minor changes to the amp are in order. Contact AA sponsor Jim McShane for details about the circuit changes and a FAIR price on the tubes.
