Well, here's some. Although there are some mistakes there.

I found some in DjVU format but cannot get back on that website - forgot what it was. The same manual though.
The 720 is said to have the same sch with
C580 or C716. While the PCB does look the same format-wise, it only has 4 tubes and ours has 5 tubes.
However C-722 sch does look similar, 5 tubes with the 12BE6 pentagrid and clock connection.
Could be it!

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
