[R-390] High Electrical hash noise level

[rbethman]

Steve,

Personally, I'd hunt for an AMP SUPPLY linear!  They came built with PW 
Dahl transformers, and a tunable toroid matching section on the input.

I've got an LK-500ZB.  It is a pair of 3-500Zs.  I added a dual blower 
on top with nylon screws and nuts.  I just want to keep the Eimac 
3-500Zs as long as possible.

Plenty of warm air with its "original" internal cooling, and the dual 
blower was meant for a 4-1000 amp project that I didn't bother with 
since I obtained my BC-610.

I've got PLENTY of heat generation available!  (Much to my wife's 
chagrin!  She starts to mumble, groan, and wave the utility bill at me 
when I light off!)  [LOL!]
