This box contains 24 crystals, 12 R-F tank coils and 12 Antenna coils, for the 1 channel radio receiver and transmitter BC-611.
In the range 4 to 6 Mhz there are 2 crystals, the receive crystal 455 Khz higher in frequency than the transmit crystal, for each channel.
The BC-611 needs realigning after changing the above parts.
