With the heavy lifting of the memory unit out of the way, I'm thinking of other things. First cab off the rank is an improved IF buffer amp…
A few months ago I posted a quick write-up of a design I did many years ago, not too long after DRM first started appearing on the airwaves. It was a pretty straightforward JFET + 2 BJT design, nothing special - but it did the job. I've never been entirely happy with it though and, since that amp has graced a friend's set for years, I figured I'd build something better for mine ;)
