The full schematic and parts list is all there. The electronic components should all be pretty easy to find and the circuit layout isn't critical as this is very low frequency stuff. The cassette mechanism looks like a standard (1-7/8 ips) drive as does the tape head. If you wanted to try building your own I think the circuit is designed to control a 6 volt (probably 4 x C cell) motor transport mechanism. These were extremely cheap and common back then.

If you do that let me know and I can possibly help with some voltage measurements, etc..
