• Anotaciones

• The General Electric P-990B is a battery/DC Power Adapter operated portable 17 transistor BC, LW, 2x SW and FM receiver.  Has fine tuning control, two telescopic antenna's and a push-pull output stage. Has earphone jack that disconnects the speaker for private listening. Also has provisions for connecting an external FM antenna and an external SW antenna.

  Band Frequency Ranges are as follows:
  LW Band.........................170 - 400kHz
  BC Band.........................540 - 1620kHz
  SW Band #1...................1.8 - 5.1MHz
  SW Band #2...................6.0 - 18MHz
  FM Band........................88 - 108MHz

  The P-990 was available in 3 different versions:

  Model	Differences
  P-990A	-
  P-990B	Different TR7-TR10 transistors, deleted R9, R32, R45, R50 resistors
  P-990C	Differences not known

  The SAMS TSM-60 calls out model P-990A only. However the SAMS index for models P-990B and P-990C refer to this same TSM-60 reference and so therefore is applicable for this model also.
