[TenTec] Titan 425 Tune Up

[Matheson, Lawrence]

    I recently acquired a Titan 425 amp and would like some pointers from
some of you 425 experts on tune up procedure.  The amp is driven by an Omni
VI into a near 1:1 load.  What should I expect in the way of grid current
and plate current readings for 1200 to 1500 watts out?  Should the amp be
initially tuned up in the low voltage position and then switched to high
voltage or should it be tuned in the high voltage position initially?
    Thanks,

Lawrence
