May 2002 DD-3(T) SERVICE NOTES Third Edition Issued by RJA SPECIFICATIONS... 2 LOCATION OF CONTROLS,PARTS LIST ... 3 EXPLODED VIEW,PARTS LIST ... 4 PARTS LIST... 5 ADJUSTMENTS ... 8 CIRCUIT BOARD... 9 CIRCUIT DIAGRAM... 10 WARNING There are three types of DD-3(T) with different circuitry called "DD-3", "DD- 3A" and "DD-3B". The pedals of all three types are labeled "DD-3". We call the new type of this model, DD-3B for identifying the old type and new type for convenience on service system. Check the model name as follows. Of the three types, only the appearance of the "DD-3" is different. Identify the "DD-3" or the "DD-3A or DD-3B" by the shape of the adapter jack as shown in the following figure. The appearance of the "DD-3A" and the "DD-3B" are the same. Due to a DRAM change, it has been changed to "DD-3B" from serial No. SO91200 of 1912LOT (produced in August 2001). It can be identified by the serial number. The "DD-3A" and "DD-3B" can also be identified by the silk-screen printing on the board. When referring to the service notes or ordering parts, check the model name using the above process. This service note is for the "DD-3B". Refer to "DD-3A SERVICE NOTES" (#17059557) when repairing the DD-3A. Variable resistor, switch and mechanical parts for the "DD-3A" and "DD-3B" are compatible. Refer to "DD- 2/3 SERVICE NOTES" (#17059183) when repairing the DD-3. fig.notice DD-3A or DD-3B DD-3 Copyright
