So I grabbed this up at the thrift store today, when I got it back home I have it a quick clean and tried powering on, but it didn't seem to respond.

Turns out it is turning on, but it is turning off nearly as quickly. I tested the volts on the power supply briefly and it shows up as ten on my multimeter (States it is 9.6 V).

Any help would be appreciated. I do have a video showing what is going wrong if needed.

The input might be fine, but there's clearly blown capacitors or the VRU is busted in the camera. Take the shell off the outside and look around where the power input is, and I bet you see popped capacitor caps or burnt wiring.

Probably somebody plugged the wrong power supply into it at some point.

I figured that was probably the case. One of the batteries that came with it doesn't match the models it supports. Didn't want to take the whole thing apart without a second opinion though

Is the battery connected while you're trying to power it on? If so, see if it'll run on the power supply without a battery.

If that doesn't help, check if there's a tape already in the deck. If so, see if you can manually remove it. A number of old magnetic media cams start to get a bit sticky/stuck and trying to move the reel or head at startup can cause them to overdraw.

If first two don't work, consider finding a proper replacement battery. If replacing the battery doesn't work, then you're almost definitely gonna need to crack it and look at replacing caps.

This goes in order of easiest/cheapest solution to most difficult, but I think capacitors are gonna be most likely on a piece of kit that old. But all the extra troubleshooting should help you narrow down possibilities before pop your new baby open and find that replacing caps still doesn't help.
