Hi all, I have a 807 vacuum tube and I want to make a CW RF amplifier with it. I am thinking of using transistors in pre amplifier and 807 as final power amp. I have only one tube so I cannot make push pull amp. First of all I need to know if it will be possible to make such RF amplifier. If possible how difficult it going to be. I need the ideas to start planning a design. I do not have any experience in Vacuum tube designs, I have fundamental knowledge of electronics. Kindly help.
