 The preset panel is a set of terminals which allows the user to rewire the C# through A presets. This panel is accessed from behind the organ.

 Here's a picture of a preset panel:

+!! Changing the Preset  
+  
+The organs which have preset panels came with a card with instructions on how to change the presets,  
+and which had a spreadsheet on which one could note the currently wired-up preset settings.  
+A scan of this card is available in the [A-100 manual|http://www.theatreorgans.com/hammond/faq/a-100/a-100.html] (figure 17)  
+The text of the card follows~:  
+  
+ <b>Preset Panel</b>  
+  
+ The tone signals from the preset keys are carried by color-coded wires to the divided preset panel in the back of the console.  
+  
+ Each preset wire, carrying a single harmonic, is fastened under a screw on the bar which represents the desired intensity of that harmonic.  
+ This is equivalent to setting a harmonic drawbar to the corresponding number.  
+ One part of the preset panel is used for the swell (upper) manual and the other for the great (lower) manual and pedals.  
+  
+ When shipped each organ has its presets set up as shown in the playing instructions furnished with the organ.  
+ Preset combinations may be changed at will by removing the console back and following the directions on a card inside.  
+ This card is reproduced below. (Figure 17)  
+  
+ <b>Directions for Making Pre-Set Panel Connections</b>  
+  
+ There are 9 color-coded wires threaded through one of the lower holes for each pre-set key.  
+ Above each hole are 9 binding posts arranged in vertical order,  
+ and above the uppermost binding post is a name plate specifying the pre-set key associated with the row of wires below.  
+ The lowest binding post is that of zero strength and corresponds to a harmonic control pushed all the way in.  
+ The uppermost binding post is of 8 strength and corresponds to a harmonic control drawn all the way out.  
+ The bus-bar strips for each level are extended to the left where they are marked with their appropriate strength numbers.  
+ For example, suppose the combination 006523411 is to be set up on the D# of the upper manual.  
+ It will be found helpful, especially when setting several combinations, to use the follow chart:  
+  
+ <?plugin OldStyleTable  
+ | Manual | Key | Brown | Red | Orange | Yellow | Green | Blue | Violet | Grey | White  
+ | Upper | D# | 0 | 0 | 6 | 5 | 2 | 3 | 4 | 1 | 1  
+ | | | | | | | | | | |  
+ | | | | | | | | | | |  
+ ?>  
+  
+ With a screw driver remove the connections already made on the D# "Upper Manual" row of binding posts  
+ and separate the 9 wires from each other.  
+ Referring to the chart above, the brown and red wires are twisted together and connected with the binding post  
+ on the level marked "0" (lowest level).  
+ Next the white and grey wires are inserted under the binding post on the level marked "1".  
+ Similarly, the green wire is connected on level "2," the blue wire on level "3,"  
+ the violet wire on level "4," the yellow wire on level "5,"  
+ and the orange wire on level "6."  
+ The binding posts should be firmly tightened over the wires to insure good electrical contacts.  
+  
+ <?plugin OldStyleTable  
+ |||^ *Color Code Explanations*  
+ ||| Each group of 9 wires is color-coded as follows:  
+ | Sub-fundamental | (brown drawbar) | brown wire  
+ | Sub-3rd harmonic | (brown drawbar) | red wire  
+ | Fundamental | (white drawbar) | orange wire  
+ | 2nd Harmonic | (white drawbar) | yellow wire  
+ | 3rd Harmonic | (black drawbar) | green wire  
+ | 4th Harmonic | (white drawbar) | blue wire  
+ | 5th Harmonic | (black drawbar) | violet wire  
+ | 6th Harmonic | (black drawbar) | grey wire  
+ | 8th Harmonic | (white drawbar) | white wire
