The Messenger I(the white face) as opposed to the "black face" or Messenger
II usually had the screen resistors lowered in value or "strapped out" with
wire. This shorted tube life. The "black face" came in a commerical version
that had a resistor left out in the power supply, allowing radio to put out
10-15 watts. I think both radios used the 7054 oscillator driving the 7061
amplifier.
