<< I have just purchased a used Titan and have wondered what tune up an power
output others see.
My observations are:
1.) It is a little tricky to find maximum output without tuning at high
power levels. 2.) Output is limited to 1500 watts(1250 on W-4) with about
60 ma grid current and .8 amp plate. Beyond that grid current goes up to
red fast and no more output is delivered.
It has two 3CX800's and 2400 V B+ supply, so I expected a little more.

Try Loading the amp a little lighter (point where the grid current drops off
quicklybut power output only drops a little) for maybe 40ma of grid current,
then increase drive, retweaking the Plate tuning. For 1500w output, you should
be around 40w drive, 1100ma IP, and 40-60ma IG on CW keydown, provided the amp
is providing at least 60-70% efficiency. Your Ip sounded a little on the low
side.....
Good luck,
