Try Sams /William I. Orr, w6sai
Radio Handbook
twenty-third edition.

Page 17-2 thru 17-6.

Think seriously about purchasing this book as it is filled with reliable information--firmly grounded in good engineering practice and ham reliable.
I wonder if anyone will ever fill w6sai's shoes? Ralph w5otp.

Don...

What do you need to know? Input circuit? Plate tank design parameters? Cooling? Give us something to go on.

One thing for sure--Plate voltage needs to be elevated to get the gain you need.

4-1000s work best at 6k and up.
