[HAM] Beating Tone

[ElSeveno at aol.com]

   One of my tones has its own private tremolo or a beating with some 
spurious frequency. I have heard this on other Hammonds. Is there a way to tell if it 
is bad filtering or a nicked tone wheel? It may even be on another tone 
(crossed wires?). It is a faster frequency than the vibrato like maybe 100 Hz. This 
organ has an official buss lube service sticker.
