All units in stock in Canada and the USA have been reworked to correct this problem. The problem is serious enough that it is necessary to modify all units in the field, so we are here by issuing a service bulletin that will be followed up with letters and phone calls to all affected dealers and distributors. All units should be modified as soon as possible. The units can either be returned to Yorkville for modification, or can easily be modified in the field by a qualified service technician. We will, of course, accept warranty claims for this modification. Required Modification: - - Remove the lid from the unit and both power amp boards. - Locate the small 0.1A fuse on lower power supply board (#M1151 - AP6040 or M1177 - AP6020). This is the only fuse in the unit. - Replace this fuse with a 5W 390R resistor (YSL Part#4736). - Dress all wires away from the two 5W 390R resistors. - In order to be sure that no damage was done to the upper power amp boards when they were removed it is strongly advised that the technician carefully retouch the solder on the three legs of each of the following transistors: #Q32A,Q32B,Q33A and Q33B on each of the two power amp boards (AP6040 - M1176/M1176A, AP6020 - M1150/M1150A) - Replace the upper boards and lid. Sorry for any inconvenience caused as a result of this problem.
