I have had extensive time using that particular LXI combo unit. It was also sold as a JCPenney MCS2230. As far as cheap all in ones were, it was one of the better cheap all in ones. It had "enough" watts to actually be useful, and with efficient speakers, it sounded perfectly fine. They could last quite a long time as long as they weren't beat on. Perfectly pleasant middling stuff has its place, too. I bet all of the belts just rotted and fell off.
You might be able to dredge up a receiver, turntable and tape deck for very little, because If she can use that particularly designed all in one, there is no user difference between it and the component stack it was designed to mimic. The initial hookup might have to be done by you, but its set it and forget it after that.
I actually have one like these out in the garage, of much lesser quality than the LXI. I think the output wattage is nearly 3 or almost 5. If you were local, I'd leave it out front for you. All you'd have to do is find the matching proprietary turntable. I just plugged it up for fun. Came right on, everything works. Listened to a tape. it sounds so bad
