Your scenario is really the only one anyone would use Doug.
The real reason is to run more than the 2.5kW output the
single tube amp would do. A single 8877 run full tilt is
cleaner than any amateur exciter made, the exception being a
class A operated MK V FT1000MP.
You also have to remember at the time that amp was designed
the legal power was 1000 watts dc plate input power
indicated on the plate current and plate voltage meters
minus the driver power. Even a single 3-500Z could exceed
the legal power at that time. It wasn't until the 80's that
1500 watts output became legal.
