  • Notes

  • The Sylvania TR22 is a battery operated 7 transistor portable AM radio.  The AM band frequency tuning range is 540 to 1620kHz.  Has a push-pull audio output stage and an earphone jack that disconnects the speaker for private listening.  Also has internal loopstick antenna and a power jack that allows operation from an external 9VDC power source. Was sold with black leather case and earphone.

    NOTE: The T1 antenna coil is held in the proper place with wax.  If the antenna coil is not held in place on the ferrite core or if the antenna is replaced, slide the coil on the ferrite core until the maximum output is obtained.  Then secure the coil in place with wax.
