Notes

From Bulletin KP-4, 22/1/1947:

"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."

Battery types used: (A) 1½ V Eveready 745 or Diamond 3745 & (B) 2 x 45V Eveready Mini-Max 482 or Diamond 3482.
