Mellotronists

Hi,   Visit a site like  Norman Leete's  
http://members.aol.com/tronpage/maintain.htm  and see his Mellotron-
Routine Maintenance, which is like looking at the 400's Owner's 
Manual (with Norman's words of wisdom added in).
I have a
Geneva VR205 290 gauss field intensity demagnetizer. It's made in 
USA. I got mine from markertek.com for about $ 59.95 U.S.dollars.
Hope this info helps,  George Summers  Houston, Texas  USA
