Hi Ed :)

   APC also makes non-SMART models.  I have no idea about what their non-SMART   
   stuff is like.  Never have even tried it.  My comment only reflects on the   
   SMART type stuff.  APC isn't the only firm that offers the SMART option. The   
   word refers to the ability for a UPS to handle this problem in the best way   
   possible.   
      
    EV> What Tubes did You used in the Finals on that KW RF Amp?   
      
   Eimac 4-400 tubes.  I originally built my first 40 meter CW higher power amp   
   with 811's.  Then moved upwards to the 4-250 stuff.  As a First Class FCC   
   broadcast engineer even back in high school here at College Station, where I   
   was working at the WTAW radio as I moved from high school forward, WTAW was a   
   1KW station.  Their transmitter had 4-400 tubes in it.  I studied the service   
   records for them at the station and really liked what I saw.  Which got me to   
   move forward to them when I was building my own stuff as I went forward   
   collecting all the 40 meter CW countries for my goal to apply for the first   
   ever 300 country ARRL DXCC award.

   Neat!   
      
    EV> I retired from a Lock and Dam and have used the Generators at both

    EV> At the Lock, when the Diesel Generator was being used, and the Lamp

    EV> the 440V 3 Phase Motors on the Hydraulic Pumps were off, I would swing   
    EV> the A.C. Power Switch on the Panel from Generator Power to Line Power.   
      
   Another little bit here, grin.  Three phase roller motors are more of an issue   
   if that is what you are switching.  Is that what an 'Off Ice' is really all   
   about, grin?  How you reaally move forward?  Which I suspect most bossies   
   really don't know anything about like you do Ed?  :)   
      
    EV> The Lights and Marine Radio and the 386 pc would come back on after I   
    EV> had switch back to Line Power.   
      
    EV> Probably the pc they use now would have to have the Power Button   
    EV> pressed because it might not be on a UPS.   
      
    EV> I don't know, maybe the powers that be have ordered UPS's for the pc's   
    EV> where I retired from. ???   
      
   Less of a problem way back then because before we went to switching type power   
   supplies. all of the receivers, transmitters, TV sets and so on had pig iron   
   tranformer power supplies in them.  As well even if you are using something   
   with a motor; that's not allways the risk issue.  Eventually you just roll   
   forward into 'normal' operation as well as eventually with the pig iron power   
   transformer supplies that just eventually build up whatever the user unit   
   needs for a DC power source.  Also the storage capacitors in the DC power   
   supply side can solve the phase error issues as well.   
      
   Enter the next generation solid state switching suppies of today.   
      
   They can be a real MESS for stuff including lightning strike damage when what   
   is supposed to be a ground wire third round pin 'protector' on your power cord   
   ain't really ground at all and can completely blow up things where it   
   transfers even thousands of volts into the 'ground' stuff on your printed   
   circuits in today's 'neat little' TV, Audio and all the modern 'we like it'   
   stuff today.   
      
   Plus .. where are we all going with NANO TECHNOLOGY in the future?  And what   
   will be argued, I suspect, as should have been probably spelled NONO   
   TECHNOLLOGY.
