Hard to say how good a square wave will look on it. I didn't look but does it have a square wave test output?
And yes, you need a signal generator that can put out a 1Khz square wave. If using a sine wave you may as well skip the generator and the scope. I made a short video to show how much distortion an amp can have without seeing it with a sine wave, then switch it to a square wave and the distortion jumps off the screen at you. If I can find that video I'll upload it to youtube and post a link. Square wave or nothing.
Oops, just noticed that it also has a signal generator in it. It's probably good for amp work which is about as basic as it gets. I've been thinking of getting a newer cheap one since all I use mine for is amps. The Techtronics is around 45 years old and the control pots are going bad.
If working on Cobra amps, you will need to input the signal after the oscillator. Just yesterday I found my misplaced worn out Cobra Cartridge that is soldered to an RCA jack. Rub my finger over the needle to make sure the oscillator circuit is working.

Hello,
Is this a suitable scope to troubleshoot Wurlitzer amplifiers? Would a signal injector be required as well?

I have only done a few basic repairs and servicing, so am still a novice.
If it can be helpful, would appreciate early response; there is time constraint to ask a friend to assist with the purchase.
Many thanks 🙏
