Don't you then require high resistance cable in order to get a near 100
percent attenuation?

I'm in a different room watching the "mechanics" working on the Hubble
Space Telescope. (Soon to finish for the day.)

Yes. The horizontal line is persistent. It was there yesterday and the
day before.

You poor *******...


What did you do to deserve that?

The handbook for the Quad valve amps of the '50s suggested that the loop
resistance of speaker cable used shouldn't exceed 5% of the nominal
speaker impedance, IIRC.

From: Instruction Book, Quad 22 Control Unit and Quad II Power
Amplifier:

When the loudspeaker leads are reasonably short, thin flex may be
used, but if longer runs are employed then the cable should be
sufficient thick for its resistance not to exceed 10% of the
loudspeaker impedance.

Ah - 10%. Sorry.

At least you're not watching it which is something, I suppose? Only a
partial punishment?

It may be better at less than 5%. Of course things have moved on since
then. An oxygen free cable in a cryogenic nitrogen-filled tube with no
kinks or tight curves held at least 12.5cm from nearby surfaces would do
just nicely.
