Yes, but my case costs will go up drastically.
The 2nd solution would cause less problems as far as serviceability as
only that high impedance portion would cause problems when serviced,
but then I still need nitrogen tanks and a way to fill all this,
astromomically increasing the start-up costs.
I know I'm nay-saying a lot of this, but I do think they are good and
valid ideas. Just not for my particular purpose and situation.
