I'm designing a discrete component audio amplifier to stand in for the one from the Soldersmoke DCR for my next radio build. The original is intentionally simple, to make understanding it easy. That makes sense.

Mine is less simple but still only 3 transistors. I'm using two BFR193s and a 2n3904. It is derived from the Soldersmoke design, so it's still single-ended, with an audio transformer. It does 85-90dB of gain (much more!) with flatter audio frequency response. #HamRadio #AmateurRadio
