Yesterday
they even incluided schematics inside of it...It was VERY
common in TV Sets...
I remember the user manual for one of my FM radio tuners. The
first page
tells you how to tune it correctly (how to interpret the tuning indicator,
etc). The next secion covers RF and IF alingment (It requires a
double-beam 'scope and an accurate RF signal generator, things that were
not at all commonly owned at the time. But it still gives them). Then
photographs of the chassis. Then parts lists. And finally a schematic.
For all it's valved with 300V HT (B+), there are no stupid safety
warnings.
