"The first production run of the 5 tube battery receiver Model 'LJ' has been modified to use a type 3Q4 tube in place of the 3V4. The modification is due to the shortage of type 3V4 tubes. Should it be required to change the 3Q4 tube to a type 3V4 tube, no circuit alterations are necessary exept for the wiring of the tube socket." Reference to 3Q4 valve in LJ-2 Bulletin.
