SERVICE BULLETIN: FEB. 20 / 2003 MODEL : YCV80 RE: POTENTIAL FAILURES OF POWER SUPPLY DIODES. We have experienced an unusual number of failures amongst the rectifier diodes supplied by a specific manufacturer. To this point in time ,we have been able to determine that we have received a certain percentage of diodes that have a weakness which surfaces after the unit has been run several times. The symptoms described by customers will be “blowing fuses” or “will not start up”. In either case it is likely that you have one of these bad diodes. When you experience this condition, we recommend that you replace all 4 rectifiers with industry standard part # 1N4007, or you can order 4007’s from us as part # 6438. We recommend changing out all 4 rectifiers in order to be 100% certain of no possible repeat failures.
