[TenTec] Omni VI Opt 1 or Omni VI + ?

[Kitchen]

I just bought that OMNI VI opt 3 from Ten Tec. I am now searching the arcives for info on how much current the VOX relay can handle. I have a Drake L7 and the control circuit is 28 volts @ 50 ma.  As a CW operator that second filter position will soon be filled and used.
The OMNI VI opt 3 is replacing a 1977 Drake C line as my main rig however the trusty Drake set will still be handy if needed!
