• Notes
• • This is a special variant of model 537U (EK2), only for 110V AC/DC, and no mains voltage selector.
  • To compensate for the loss of output power associated with low anode voltage, the output stage is set up in push-pull and a stronger rectifier is used.
  • The coupling between the 2 AF stages is done by a transformer, which does also the phase inversion for both output tubes.
