What I don't understand about this choke (inductor) in parallel to the mains line is this:
The power transformer primary coil in an amplifier is an inductor in parallel with the mains line. I don't know how much inductance there is in a 1200VA transformer. Would it be about 5-10 Henries?
I don't know if the concept makes sense to me because I don't know if a big inductor can store and release enough current to smooth out the line voltage.
What is clear, thouigh, is that such a device as the Hammond 193L, with its low series resistance, should eliminate DC on the mains line - a good thing to do, as DC can make transformers buzz. However, since parallel inductance make a high-pass filter, it can do nothing to remove RF hash from the line. It seems like RF hash is the worst enemy, so why should this inductor be any good to us?
Don't we already have such a device as this in our big power trannies, and isn't the whole concept sort of ambiguous besides?
I sure would appreciate any light on the subject...
Cheers,
