Anybody have any idea what the current draw on the original backlight bulbs on a TM-733A might be? I found some bulbs at RS that will fit physically that are rated 12v @ 60 ma. I don't want to tax the 1.2 amp fuse link on the main board. This info might be in the service manual but unfortunately I don't have one. Any help would be appreciated. Thanks. Paul, N5PS
