    The Scott Allwave 15 is an improved version of the Scott Allwave 12 Deluxe.  The major improvements are the addition of a tuning meter driver tube, BFO, and push pull 2nd. audio stage.  The output wattage was increased using a pair of 2A3 in place of 45 tubes in the final audio output stage.  There were two versions of the Allwave 15, the early version had the 55 2nd detector tube set up as a half wave R.F. rectifier while the late version had the 55 2nd detector tube set up as a full wave R.F. rectifier.  I acquired this set in 1989 in a trade, of a Scott Worlds Record Shield Grid AC 10, with a prominent Scott collector in California.
