This is unrelated to your stated problem, but FYI: BEWARE of the huge
current surge in the amp's ant relay key line!! My ZB has a factory mod
upgrade kit installed which lowers the surge on that keyline to a much
lesser amount. But it's still way too high for the OMNI-6 to pull up the
relay. I do it an outboard way.

>Plate current does not change with or without drive (when relay
>Same cabling when hooked to my AL80B amp, works like a champ.
>The LK500ZB is non QSK .. same for the AL80B
>Zener diode replaced.
