Ok, hello out there to all the technical guru's!  This is Doug, K4LT and =
I am NOT much of a technical wiz.  Can anybody help me?

I have my Henry 2k Ultra on the workbench and am wondering two things =
(it has a pair of 8873's in it)

1.  Is 700 watts output normal for this amp?  Should I replace the tubes =
to get - say 1,200 watts or even 1,500 watts output?

2.  When replacing the tubes the manual says apply heat compound to the =
tubes to bond them to the heat sink blocks.  It specifically says not to =
use silicon compound.  What is heat compound?  Where to do I find it?  =
Any special handling required?

Thanks in advance for any replies.
