Kind of answer my question regarding Dynaco ST70 A470
OPT primary inductance ...Due to global negative feedback, output impedance is scaled
by a factor of 1/(1+ beta * mu).Plug in some numbers for ST70, mu = 16, beta = 1/5 (not sure ??).
Impedances are scaled.
The criterion:
OPT primary impedance > reflected load impedance
is valid.Make sense ?
