I would love to see pictures of your Oscope! 
You can use an arduino (I think ) as A signal generator.
Arduinos cost about 20/30 dollars.
Here is A link:http://www.amazon.com/s/ref=nb_sb_ss_c_0_7/188-5010419-9324448?url=search-alias%3Delectronics&field-keywords=arduino&sprefix=arduino%2Caps%2C183

You can make your own PSU from an old ATX CPU PSU.you can ATX PSU'S In old computers.
G D Luck!

Here are some photos, the scope is in really nice condition. As far as i can tell, it's also working perfectly. I don't have special test equipment, but it works for anything you can throw at it with a DMM and an Arduino.

That is A better OScope than I have!

I have A B&K Precision Model 1474 30 MHz Oscilloscope.


Old and vintage and needed tweaking.

Your scope looks like the one Dave found for $19.

He wants a linear supply. Not a noisy switching type.

Then use A 7805 voltage regulator.


This guy is giving away one:https://www.eevblog.com/forum/buysellwanted/free-30v-1a-15v-2a-bench-psu/

To the OP: I would just advise you sell this scope, and purchase a nice, used Agilent supply. Maybe even broken, as they aren't all that hard to fix.
