Fields,
Tube testers electronics-wise are fairly simplistic. What makes them complcated is bunch of switches, but in Knight 600A there is only one rotation switch and bunch of on-off switches, so cannot be that complex.
A sch is always good to have but is not absolutely necessary. I am sure some folks here keep some weak tubes around and you probably coul have them for asking and possibly a shipping charge....
