Check the serial number of your scope against the manual as I think that there are several types.
On a positive note. Mine had seized so I dismantled it, cleaned the bearings by forcing iso propyl alcohol into the bearings followed by light oil until they were smooth. It then ran beautifully. A very nicely made motor.

Hi, new member here. Hope this hasn't been covered before. Anyone know what the fan motor voltage is for the 454A? Mine is starting to make funny little noises. I have the service manual but it doesn't show the voltage and current. I can see from the schematic it's an AC motor. I'm thinking of replacing it with a small muffin fan when the time comes. I use this scope daily in my work so I want to keep it running a long time. Also have a 575 and a 7903. These Tek scopes were such hi quality! They were the standard others tried to live up to when I was a kid in school.
