 Electro Music (and later CBS) did not provide factory kits to connect so-called "universal" or general-purpose Leslies to Hammond console organs without internal speaker systems. 
 This was done to protect Hammond dealers who, at the time were responsible for most of 
 Leslie's sales. 
-Any music dealer could sell 147s and other general-purpose Leslies, 
-but only Hammond dealers sold Hammond-type Leslies like the 21H, 22H, and 122. 
-However, the 147 hookup is relatively simple and re­quires only minimal technical expertise.

  # A self-powered preamp (with a power transformer and 6X5 or 6X4 rectifier tube)

 The installation will be neater and safer if the six-pin socket is installed 
 in the organ's outlet box.

 Set the _LoadSwitch_ in the Leslie power amp to the "open" position. 
 This completes the hook-up. 
 If a 122-type "half-moon" switch is used, it will work backwards with 147-type Leslies.
