The Leslie® Speaker is widely acknowledged to be a key component of "The HAMMOND Sound." However, properly connecting one's Leslie to one's HAMMOND continues to prove difficult to many. HamTekker Harvey Olsen of Chicago fame graciously provided a list of all of the "Leslie Kits" made through the years, listing which "kit" is used to connect a specific Leslie speaker to any particular organ. 6-pin Leslie Series: 6H = Hammond-type Leslie Models— Includes: 30A, 30C, 31A, 31H, 21H, 22H, 22R, 122, 122R, 122V, 122RV, 142, 142A, 222, 222RV, 242, 122A-T and current 122A. (Early "30" series models below serial number 5200 have no provision to isolate DC control voltages and can not be used with 6H-type hookups unless their power amps are upgraded to later specs.) 6W = Leslie Models based on the old Wurlitzer wiring standard — Includes: 31W (except very early version), 44W, 46W, 25, 45, 47, 47R, 110, 112, 114, 116, 120, 120C, 125, 225, 145, 145A, 147, 147V, 147RV, 245, 247, 247RV, and current 147A. (Spinet-type Leslies without power amps have their speaker(s) connected directly to pins 1 and 6.) 6C = Leslie Models based on the old two-channel Conn wiring standard— Includes: 50C, 55C, 51C, 51, 251, and 351 (Model 55C has no motor control and works only with selected early Conn Organs) KIT # Leslie Type/Model to Organ(s) 1122 6H to organs with 11-pin outputs (powered preamp, current kit)
