AS many of you have noticed, the Leslie 122a and 147a are not the same as the original 122 and 147. Several things like a styro foam bass rotor, pulse modulated motor and driver board componets have replaced the the supper dependable older motor drive systems. Even the horn bearing lasts only a few years. Why, so they can be made cheaper of course.
I have been building my own Leslies for years now and here is the end product. It costs no more than a new Hammond Suzuki Leslie and is built to last. The old way! And it can be ordered in whatever finish you want and it can be built into the shorter 145,142 cabinet and it can have a heavier than normal bass speaker. Yo pump up that low end.
