This then prompted me to wonder about the uncoupled inductances,
parasitic capacitances, etc, that would allow someone to estimate the
actual bandwidth in use of the transformers. Since you quoted the 80H
I wondered if you knew the other relevant values for your
transformer...


The reponse is 10Hz to 100kHz +/- 0.5dB at all settings. THD is 0.05%
driving at +18dBu 50Hz.

With what assumed/.chosen source, load, and cable impedances? e.g. does it
assume a 600 Ohm source, a 10k load, and ignore cable capacitances?

I assume you mean "not less than" for the values you quote, since the real
values could be expected to vary with the tapping. (?)

The 'Silk' transformer data seems to say nothing about parasitic
capacitances, etc. Not about the winding resistances. Since they claim a
very high inductance and imply they use many turns of tiny wires, I wonder
what the levels of these parasitics might be.

Slainte,
