Eico 460 Oscilloscope

[darklife]

Thanks for the replies so far. I will look around my junk boxes and see if I can find an old transformer that will work as a "bucking transformer". I just don't feel comfortable with how warm the power transformer runs but I don't know maybe it was made to handle that much heat. It gets almost too hot to touch after an hour of operation while inside the cabinet.
I have had a lot of older scopes in the past but this one is by far one of my favorites for some odd reason. It's simple to repair and gets the job done for basic audio testing and some low frequency RF work. Could always get a new scope but I like antiques what can I say

Another problem I notice is that on a few of the sweep selector ranges the waveform gets more narrow toward the left of the CRT, and wider toward the right. Just enough to be noticeable to the eye. I wonder if the sweep oscillator needs a tuneup or maybe has an old capacitor that is acting funny?
It only seems to happen on the 1-10k range.

I don't really have any other projects going for me right now so I plan on tinkering around with this until it works really good. Do a few modifications to make it run better and recap it so it runs as new. Besides this is teaching me a lot about the internals of how an oscilloscope operates so it's an educational project for me.

Any further ideas or suggestions are appreciated.
