That's usually how a common base amp works - still not sure it works as I expect though :) https://www.electronics-tutorials.ws/am ... ifier.html
I have no idea what I was thinking with the common base arrangement.. That’ll boost voltage, not current.. hope the powers that be don’t revoke my radio amateur license :oops:

Common collector should be the way forward - load connected at the emitter, input V at the base.
