• Model: Ultradyne L2 [UX tubes] - Phenix Radio Corp.; New York

• Shape
• Tablemodel, Box - most often with Lid (NOT slant panel).

• Notes
• The Ultradyne L2 was first manufactured for the UV201A with thoriated filament, which was announced in December 1922. In August 1925 the UV201A was withdrawn and replaced by the UX201A. We therefore show two variants of this model for Keystone, UV201A and UX201A. They have later also been fitted with UX112, UX171 or UX171A but we don't put that into the tube line up as "or" because that was at least a year later of the UX201A variant.
  
  Two dials (primary tuning control knobs).
