Due to post war shortages of 3V4 valves some models were supplied with 1Q5GT or 3Q4 output valves. Also, again due to shortages, some models had the 1T4 valve the in I.F. stage substituted by a type 1L4, with no circuit changes.

"The second production run of the five tube portable receiver Model 'KP' has been modified to use a type 3Q4 tube in place of the 3V4 tube. 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 except for the wiring of the tube socket."
