*WARNING*
THERE ARE HIGH VOLTAGES PRESENT IN THESE DEVICES THAT CAN KILL YOU
USE CAUTION!
I think this is where I'm going to gather info on the 'scope, but this blog is currently a test as it is my first attempt.
You can see here it's pretty ancient. I would not recommend even plugging this in without replacing the caps personally. At the very least, a Variac should be used to turn it on, and the "light bulb test" would be a good idea prior to that. Phil's Old Radios has great info for the beginner working on old tube gear like this. I also recommend Just Radios for replacement caps. They have nice selection, prices and good service.

| Old paper caps, dust and dirt. |
 |
| All new caps. The mulit-section vertical caps were the hardest to replace. You can see the 3 new electrolytic caps grouped together to the right in the background. |
 |
| I had to remove the CRT to replace the cap on the Horizontal Frequency Selector. You can see that cap in the other pictures above (top left). That big multi-section cap in the back is still in the unit but disconnected, with the replacement caps mounted underneath. |

Working nicely. Bright stable trace from the 1v p-p output! |
