Homebrew RF Power Amplifier

RF Power amplifier based on the W6JL amp. The intent is to use readily available parts in the first instant. These may be swapped out depending on how well they perform.

See YouTube for videos.

The original circuit (minus the biasing RFCs)

My version of the bias network

The final amp has used a BN-43-202 for T1 (8:4) and a BN-43-3312 for T2 (1:3). I also left off the RFCs for the YouTube video. Adding the RFCs would increase the gain a little.
