Tom,

The TW-1 current draw is minimal.  The 998 auto tuner  needs 1.5 amps 
for tuning, but  while the tuning process is going on the radio is only 
putting out 10 or 15 watts, so current draw by the radio at this time is 
  low.


If running the amp, you are probably only driving with 50-60 watts, 
depending on band, so  plenty of headroom for the ps.

If you are going to obsess about the power supply, maybe limit your 
barefoot operations to 80 watts.  The other station will never know the 
difference, and you will sleep better.

I think this supply will suit your needs, but don't think I would  add 
more stuff to be powered at the same time.

73, Steve KW3A
