I'll go peruse the archives again but I'm going to post this here anyway.
I noticed while on 20m tonight running about a kw that the tank coil was 
getting 
HOT, one of the wires connected to it (the 20m section) was turning a nice shade
of darker! the coil is warm.
 
also When I pulled the cover (I was looking to see where all the hot smell was 
comming from)
I noticed that a doorknob cap I have installed next to the load vacuum cap was 
also warm!
i'm using that cap to get me on 80m its in parallel with the 1000pf vacuum cap
 
everyone I talk to with it said they notice NO noticible difference when its on 
or off only
a few s units higher! (no audible distortion)
 
the cap I am using is labelled n4700   591m 30kv  706h and has a c with an m 
inside of it.
 
are these suitable for what I am doing? hell, its 30kv! why warm? what should I 
be looking for?
the amp seems to load up pretty good into the vertical with an swr of less than 
1.3 to 1
 
thanks for any help
