Are Pentax K-mount teleconverters universally compatible with all K-mount lenses?

I'm coming from Fuji's X-mount where their native TCs only work with a small handful of lenses. I have an opportunity to pick up a vintage K-mount 2x TC (Teleplus MC7) for pretty cheap, but I'm wondering if it'd be compatible with the other K-mount lenses I currently have and any other possible ones I'd pick up in the future. I don't care about lack of AF since I'd be using it on an old film SLR, but I figured since I'm asking about the mount that this forum would still be acceptable.

So, title - if I buy this old TC, can I use it with any (or at least any first-party) lens?
