Sorry to burst your bubble chap, but the records Vinyl uses would be compatible with a gramophone, since essentially it exactly the same type of record player. The only difference is that a gramophone hasn't got as many electric gizmo's as a new age record player.
Well then here's a suggestion for a drawing: A purple chimpanzee eating Banana Bread with Octavia at a dinner table while Vinyl Scratch (In bib) is standing on an ceiling fan (With the ceiling cracking from her weight though she doesn't notice) as Octamum tries to get her down.
I was about to ask the same question, but then I realize the question was already answered. Of course Octamum was behind this! Who else could it be? And of course Vinyl getting on Tavi's bad side will come back to bite her in the butt, very soon.
Just make sure you get enough sleep so that you don't start coming up with sillier ideas, like posting art of naked ponies.... oh wait...
Tavi's expression is priceless XD She's been putting up with a good bit from Vinyl lately (though with her mother I'm sure she's at least hardened somewhat to such treatment X3). Wonder if Octavia ever does anything in retaliation?
