• Notes

• The Philco Model T-9 (Code unknown) is a Battery operated 9 transistor portable AM Receiver. Frequency Coverage is 540kHz to 18.2MHz seperated into seven bands:
  Broadcast: 540-1620kHz
  Shortwave 1: 2.0-4.0MHz
  Shortwave 2: 4.0-8.0MHz
  31 Meter: 9.4-9.9MHz
  25 Meter: 11.4-12.0MHz
  19 Meter: 14.8-15.6MHz
  16 Meter: 17.2-18.2MHz
  This model has Qty(1) 5.5" PM speaker. Earphone jack disconnects the speaker for private listening. Uses Qty(4) 1.5V D cells for the main 6V supply and Qty(2) 1.5V D cells for a separate stabilized oscillator supply to assure minimum frequency variation. Cabinet is Leather-like material over wood. Philco's first transistorized shortwave portable radio. Dial is unique in that the logging scale slides below each band as it is selected.

  Compare with models T-9 Code 124 and T-9 Code 126 with partly different transistor line-up.
