I have a 50 Watt Marshall JTM50 PT with 4k2 prim built in the Liverpool clone and sounds very good.
Now I found another PT in my box with 6k but only 30 Watts from a Engl 601 Jive.
Both primery impedances are measured by known measurement with signal generator 1kHz/0,5VAC /VOM/calculator.
I´m not in the position to check out both sounds because my possibility for playing loud is very restricted.
So I would accept for the moment a theoretical view too
What do you mean?
