Why so many tubes?

@czarivy

The speed of your car is not dependent on its cylinder count.

Not a troll thread at all. Seems like a complicated way to reproduce music. And yes a little bit of laziness involved, but electrical engineers make lousy writers as the subject is a difficult exposition. 
So some of tubes are the same as the power transformers? And I am open to SS to being more complicated. 

The speed of your car is not dependent on its cylinder count.

But more importantly there is a general relationship between the number of the cylinders and the output horsepower.  It's actually a good analogy.

Respectfully, the idea that the number of cylinders in an automobile has a relationship to horsepower is NOT a good analogy... Let's consider a modern V-12 power plant say from a Bentley or Aston Martin. Now, let's compare that to a V-8 funny car or top fuel dragster. Or an F-1 motor.

Ridiculous comparison, yes? Of course, you need to take into account displacement, air/fuel delivery, torque delivered, etc. which are VERY different in the above examples... however the number of cylinders has little to do with ultimate power output but does have to do with HOW that power is delivered...

Happy listening.

This might reflect a little common sense approach but shouldn't the designer know how many tubes to use.
