  David Grimes writes in "Radio Design" about the Pilot A.C. Super-Wasp on page 3 to 15 and 28ff. The Pilot AC Super-Wasp - in this magazine the front plate shows Super Wasp without hyphen - on the photo of Manfred Edelmann you can see with hyphen which might indicate that there are different versions around. The article deals first with the big difficulties to get a hum free "telephone receiver" also for short waves and with regeneration. It shows also the difference between the tubes 227 and Pilotron P-227 and it gives detailled information on the kit.
  
  The AC tetrode UY224 was first announced in April 1929 - and only later followed the 24A. The model with this tubes can not be before 1929 [EE].
