I could be wrong but I doubt that it will work. It looks like a variation on the DSO138s I have and they are absolutely useless for anything but audio. They are rated for 200k but can't even properly display a 25kHz PS drive signal. You can try it but don't be surprised if it doesn't work.
Define 'scope'? I can tell you definitively that scopes like the DSO138s I have absolutely do not have enough bandwidth to display a 25kHz square wave. Without being able to properly display a square wave properly, the scope is useless and could be so misleading that trusting it could be worse than no scope.
Do you have a laptop computer or a desktop computer that you will have on your workbench?

The OWON VDS1022I (<<< the I is very important as it signifies 'isolated') is the cheapest scope that I've found that will do any useful work.
You should see if the one you have works before buying anything else.
Do you have any other amplifiers that you could test your scope on?

Excuse the quality of the handheld images.
This is what my cheap scope does. The low frequency is 20kHz (10us) The high frequency is 80kHz (2us). 80kHz is just about the lowest frequency that class operate at and you can see that the cheap scope cannot properly display it. The OWON does an acceptable job but the CRT scope gets it right (clean and clear). I know CRT scopes are a luxury nowadays.
What other amp do you have that you have to check the scope with?

Yes if it's in good working order.
People think you need a 100MHz scope but a 10MHz will work perfectly. The comparison at the following link shows the difference in the waveforms with a 2MHz (not a typo) and a 100MHz.

I can't guarantee that we'll be able to get it repaired but that scope will help.

Understood.
Thank you
I may have access to a schematic tomorrow.
Where can I learn the process of using the o scope for this application? I've never used one..

You can start there ^^^. There is some flash but enough other information to get you started. One of the most important things is to use DC coupling for most everything.
Did you order it?
Don't let all of the controls confuse you. After getting it set up, you only have to change two controls and those are typically only between one of two points (especially if using 1x/10x switchable probes).

I don't know what that is. If you need a different probe, you can get decent switchable probes on ebay for about $5 each. They look like the attached image. Buy at least two but I'd suggest getting 4.
Also learn to use it in differential mode. If you don't know what is, I can post the setup for it.

Did you change your mind on the other scope?
If the specs are accurate, it would work but (personal choice) I'd prefer to use a 50 year old CRT scope over any of the LCD scopes that I've ever seen.
