Offering a circuit extender for use with the Heathkit HR-1680 receiver complete and ready to use.   This extender is used to extend the plug-in boards so they can be serviced and/or repaired.  

This extender is being offered in three sections to increase versatility and ease of use:

These board sections cross over to some of the boards of the Heathkit SB-104 and HW-104 transceivers.

With three sections as apposed to one single board, sections can be used to service the HX-1681 transmitter.


Thank you and best regards
