Amplifier key Line buffer

I acquired a nice SB-220 in a trade and needed a TX Line Buffer, I went in the kitchen and made a ham sandwich to empty the lunch meat container that I used for my project box.

I like that "Ham" sandwich!
Buffering in always a great idea.0 -
Make sure you have a diode and a small cap across the coil so you don't zap the pass transistor in your Flex.
