Yes, you could wire it like that.
Thats the neat thing, you could also use one of the sec windings to drive a VU meter, or use the amp as a mic splitter, etc.
You can vary you inductances by connectong two windings in series for either/or the pri or sec, many different combinations.
I think the normal hookup is one primary, and three secondaries.
Then you can series two sec windings and use the third for metering, etc.
I don't know if loading down the extra secondary with a vu meter will affect tone or not.
I still have to build mine.
