Get an O-Scope made by Tektronix (mine is a 2205). You won't regret it. A 20MHz or higher bandwidth will be more than enough for audio. Tools that try to be too many things don't work for me. As with audio, separate devices are the way I go.
I'm using a Heathkit audio signal generator that I built in the early 1980's. Someone will have knowledge of current models and manufacturers.
If you don't have a multimeter get a Fluke. It's another purchase you won't regret.

yes, and easier to repair separate devices

I'm good on flukes. Have 2 (I with amp clamp) in Ohio and 1 in Florida. I don't have a good quality analog multimeter, just a old realistic radio shack one. It's good for testing a sweep on potentiometers to see drop outs etc. but a scope would probably replace the analog meter. Thanks.

I'd go with something a bit more traditional
Yes, I asked for suggestions and thanks for everyone's input. I don't know enough about scopes, to know if the automotive scope would work. My scope knowledge is only automotive. It's already paid for years ago, so was hoping to use it until I find a good acceptable one that was suggested by you guys. Now I know what to look for. Thanks.
Check the specs on that automotive scope. If it can only handle like 15 or 20V it might not be able to handle stereo-level power. 20V RMS is 50 watts into an 8 ohm load. Otherwise it might be usable. Worth trying since you already have it.
Most scopes with built-in signal generators aren't going to go down in amplitude as much as you'd want for testing stereo inputs. You could use an attenuator. You're looking for something that can go down to about 2.5mV to test phono inputs or about 150mV for testing other inputs.

What does a new suitable scope cost? The tectronics on epay all are used and most are as is, or not tested and missing probes. Are they same as stereos and repairable with capacitor, resistors, diodes and transistors etc. Just rather save up and pay for new one, unless suitable ones are outrageous new. Looks like $200 bucks and probably another $200 for parts and testing probes if you go the used route. Just wondering. Thanks.
How about something like this:
FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator, 2 Channels, 10MHz Bandwidth, 50MSa/s Sampling Rate
FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator, 2 Channels, 10MHz Bandwidth, 50MSa/s Sampling Rate
You can get a pretty good new scope for about $400 with probes, maybe a little less even. I have a Rigol DS1102E that works well. It was around $400 when I got it but looks like they're around $450 now. There are probably some better ones out there now though. I haven't kept up on all the new models.
An old analog Tektronix is still really useful if you can find one cheap. But ebay isn't always a great way to find them cheap.
