 !Hooking a 122 to a spinet 
+  
+The 122 was designed nominally to connect to Hammond console organs which have balanced [G-G] outputs.  
+Hammond spinets and other brands of organs do not have balanced outputs. This complicates matters somewhat.  
  
 Here's the schematic of a 3M kit, which is used to hook a "122 tremolo control kit" (see above) to a spinet. If you are clever, you can figure out, from this schematic, how to hook a 122 to a spinet without the main-echo switching.

 !Transformer-less Leslie Kit 
  
 As described above, the stock [LeslieHookupKit]s use an isolation transformer to isolate the [G-G] outputs from the common-mode DC control voltage. One can, of course, use capacitors instead. 
-BradBaker has a schematic detailing how one might do this at:

 MikeFulk says the addition of two 0.02 uF capacitors to ground from either leg of the signal path _after_ the 10 uF NP caps is absolutely necessary to the quiet and balanced operation of the circut, and will engender its working perfectly. 
  
 There will be no perceptible degredation of the sound, says Mike Fulk.
