• Notes

• The Scott Allwave 15 was introduced in 1934 and was designed to replace the earlier Scott Allwave 12.  New features were the addition of a tuning meter driver tube, BFO, and push pull audio driver stage.  The audio output was increased by replacing the push pull 45 valves with 2A3’s.  There were two versions of the Allwave 15, an early version which had a 55, 2nd detector tube set up as a half wave detector and a late version which had the 55, 2nd detector tube set up as a full wave detector.
