Hammond Tonewheel Organs

Early in 2008, I was bitten by the Hammond organ bug, resulting in the acquisition of a 1962 Hammond M-111 spinet. Like all Hammonds of this vintage, it features an electro-mechanical tone generator, harmonic drawbars, and a vacuum tube amplifier. Here I document the work I’ve done to get this organ back into shape and to keep it that way, enhancements I’ve made along the way, and my discoveries about the operation of this piece of musical history.
