My 576 works well except that a few of the #683 bulbs that illuminate the fiber optic scale factor readouts are burned out. The service manual is quite terse on the procedure to replace them, and completely ignores the situation where the burned out bulb is on the front readout circuit board.?
Does anyone have any practical experience and/or tips on how to replace the bulbs, on both the front and rear boards, with a minimum of risk to the fiber optic bundles?
Thanks,
Stan
