[Amps] Homebrew is back..

[Lou Spradling]

It has been several years since I have attempted to "build something",; and in 
that frame I become an (operator). A real pleasure to pursue the hobby with 
researching material for 10-160 linear amps ! and in doing so I discovered this 
reflector !! Wow, a real goldmine of experienced builders in my library'.  It's 
great.

Now, my problem is trying to locate one or more Tubes 4CX1600b for a Ten-Tec 
Titan II, OR. any thoughts or suggestions as how I should approach this item. It 
is working fine but it looks like a little rework of the final area  will be 
required if I can locate a tube that I should use.?

Please, any information would be _greatly appreciated.

Thanks to all.           73's  Lou
