[Amps] Henry 2KD2 Amplifier

[Gudguyham at aol.com]

The 3-400 tube will make just as much power as a 3-500 on SSB with a lower  
duty cycle, the plate dissipation is a little less that all.  They require  
less bias.  The problem with that amp is they must take an old style 3-400  
without the phenolic pin support because they are a bit taller.  The 2KD is 
 very tight with the tubes and there is not much headroom not only for the 
new  style 3-400 but doubtful for a 3-500 conversion, other than that it is 
a well  built amp, however many amps outperform it at lower cost and weight.

Hi  Everyone,


A friend of mine has an opportunity to buy a Henry 2KD2  amp. Now I know 
Henry kicks butt,
but I see that this amp uses 3-400  tubes.
So,not knowing alot about these tubes and this model of amp (I know  the 
2KD uses 3-500z's)
I am curious if their are any caveats or what power  to expect out of this 
amp? 
Also...like people's opinions of this one. Can  you still buy 3-400's? 
Any info on this amp would be greatly  appreciated.


73 and Happy New Year!
