Subject: Re: [Amps] Henry 2K-4 Failure Thanks Jim, you can't beat words from 
those experienced.I guess a cathode test plug could be made to substitute one 
tube plugging intothe socket .A dead tube could have its base made up for this, 
with resistor added tocathode connections equalling the hot value.Then 
interchange tubes on the remaining socket to compare.vk4tuxOn 20/3/20 3:32 am,

 The  grid  to cathode  short  only  happens  with  tube  fil  lit.....  not  
when  cold.> When  cold,  both  a HI  pot  tester....  and  also  a megger  
wont  work  either.>> Jim    VE7RF>
