Hi All,

I've gotten several inquiries regarding building or converting HF 
amps using tetrodes such as Svetlana's 4cx400a, 4cx800a and 4cx1600b, 
as well as others.  

The optimum way to handle such a project is, in my opinion, to use 
the G3SEK "tetrode boards." They include protective circuitry, bias 
and control power supplies, and just about all you need except a 
plate voltage supply and RF deck.  They have an optional transformer 
which will provide the necessary screen grid, control grid, relay, 
etc. voltages.

Information on the boards and where to get them is available at:

http://www.ifwtech.demon.co.uk/g3sek

or by going to Svetlana's homepage:

http://www.svetlana.com 

and clicking on "related websites".

I wish I'd know about them before my last project, the 4CX1600B that 
appears in the '99 ARRL Handbook.

I am not affiliated with Ian's "tetrode boards" production or 
sales... I'm just a customer.

73,
George T. Daughters, K6GT
