[Hallicrafters] Help Identifying Unknown Part

[pete wokoun, sr.]

Ed,
  There's supposed to be a rectifier between the transformer and positive 
filter capacitor.  The original was probably selenium.  Just use a standard 
general purpose 1N4007 silicon diode there (1 amp/1000 volt), anode to the 
transformer and cathode to the filter cap positive.  The original only had a 
30 mA rating so a 1 amp diode is plenty.  I couldn't figure out where your 
pictures were from the address you gave.
