Having repaired a few CRTs, this whine typically only happens on aged parts. My son can hear it, but I cannot. From what I understand, as the coils move from vibration over time, this whine gets worse, calling for realignment.
The odd thing is I don't remember hearing it much as a kid in the 90's, which is why I associate it with the age/condition of the equipment. These days, every CRT I bring home is the bane of my son's existence if he is in the shop with me, but I can't hear a thing (due to the age of my equipment)
- NikkiA 3y agoI definitely heard it in the 90s, in 1990/1991 my university had a lab full of televideo 910 and 905 terminals that were maybe 5 years old, suffering from massive burn-in and a lot of them whined really bad, giving me a headache if I had to use them (the 905s seemed to be worst at this). My first job also involved a dec vt240 with the same features - really badly burnt-in display and horrific coil whine that made me go home with a migraine at least twice that I remember.
