[Amps] Difference between Henry 2k and 3k?

[Joe Isabella]

I dont know about the 2K & 3K specifically, but I do know about the 3K-A & 2K Classic (and Classic X). The 3K-A puts almost 4kV on the 3-500s, the 2K only about 3kV. The Classic X puts about the same power, but has one transformer where the 3K-A has separate Fil & HV transformer (like mentioned below).  It also has a tapped inductor and two variable caps where the 2K Classic(X) has a variable inductor.  I prefer the tapped inductor for easier band changes.  Also, the 3K-A has an extra bandswitch position (perfect for adding 160m), built-in step start, and a slightly larger (it's deeper) case.  However, it has no "Standby" position (it's either on & inline or off & bypassed), but that's easily fixed with a switch in the keying line going to it.  There's probably more, but I can't think of it off the top of my head.
   
  Didn't the Original 2K (no suffix) run 3-400s?

  I see.... I guess still a workhorse today! I'll have to go look and see if 
it's a roller inductor or tapped (from a WARC band perspective, the roller 
would be nice!)

Thanks for the good info!
