[Amps] Source GU-84B fil xfmr

Roy, even though no inrush protection is called for, it can't hurt  
anything.
 
Over a 35 year period of using an 8877 on 2m EME I have lost two tubes;  
both had an open heater. I have to believe a surge limiter might have saved 
one  if not both of these tubes.

FYI  all,

RFP part #F-41X for $9.95 each, is rated 26.5 volts @ 2 amps with  120 VAC 
on 
primary. I purchased two and connected primaries in series with  
secondaries 
in parallel. My 247 VAC line yields 26.96 volts for the pair  with a 4 amp 
resistor load. I'm planning to convert my Titan-2 to a  GU-84B. Any 
thoughts 
on whether or not an in-rush circuit needs to be used  with this indirectly 
heated cathode tube? I read somewhere that the  original 4CX1600B specs did 
not call for any in-rush protection.  Thanks.
