	I was thinking about buying a Svetlana 4CX1600B High Performance
Tetrode. Its a ceramic/Metal Tetrode that can disipate up to 1600
Watts. This tetrode is is used in high gain grid-driven RF amplifiers. 
I need to get Abode Acrobat to read the spec. sheet for particulars
though. The Devil is in the details.

	I'll also get that catalog from Vacuum Tube Industries.
	Any comments are always welcome.
