One thing I was wondering was if I use a transformer

a nominal 16 ohm secondary but use it with 32 ohm

secondary would be so low relative to the load that the
output could be considered essentially a voltage source.
Equally the load reflected to the plate would be four
times higher so distortion would be lower?


Language. Lower load = higher resistance.

If you follow my logic, my point is clear. The load
presented by the primary of a transformer comprises:

1. Primary winding resistance
2. Leakage inductance in series with 1
3. Reflected secondary winding resistance in series with 1
and 2
4. Reflected secondary load in series with 1, 2 and 3
5. Primary inductance in shunt with 3 and 4

Think.


Nope, maybe I am just thick. You said "10H is in shunt with load. Lower load makes shunt more
significant."

Now you are saying "Language. Lower load = higher resistance."

Which means "Higher resistance makes shunt more significant"

That means to drive a higher resistance load I need MORE inductance in the primary.

Does not make sense to me.
