Trek II GNR-1A

Trek II GNR-1A

A cost-effective alternative to removing and disassembling Hammond tone wheel generators when defective frequencies are encountered.  Simple three wire installation.  Generates a sine wave output of any tone wheel frequency.  The GNR-1A has a built-in power supply and will replace one frequency.  If additional frequencies require replacement, optional GNR-2A units may be added to the GNR-1A.  As many as three GNR-2A units may be powered by a single GNR-1A.
