Your serial # is in the range that had the "Good" Black silicone potted HV XFMR. The "BAD" ones are B024999 and below. Printact Relays are always a problem with the 576. Dim or burned CRTs are another. There are a ton of filter capacitors in these things, especially the power supply that can and do go bad. Dirty and sticking switches are another huge issue. Most of this can be fixed if necessary. Checking the calibration is also essential as there are many adjustments that can drift over time.
