A method of changing the source of the zone power from 100 volt to 70volt The Yorkville CA1 commercial install amp has both 70 and 100volt capability. When a customer wishes to convert the zone output from 100 volts down to 70 volts, he may follow these easy steps to modify the supply board which is the middle of the three barrier strips on the rear of the unit. 1) remove the main chassis cover 2) while facing the rear of the unit, remove all 3 of the speaker terminal strips 3) the top and bottom strips will come out easily but you will probably have to unsolder and remove the yellow varistor from the middle terminal strip. This is a little tricky because you will have to unscrew the middle strip and flip the amp over to gain access to the solder on the varistor. 4) Once the middle strip is free of the chassis all you have to do is cut one trace and add one jumper as shown in the following before and after photos.
