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. Manufactured in USA by Trek II

NOTE: The GNR-1A and GNR-2A are not usable to replace pedal frequencies on spinet organs, since these tone wheel outputs are not sine wave signals.
