TLDR is I'm looking to re-use some parts for a low powered mid/hi-fi stereo amp, asking for feedback on design ideas. I have been using my Bassman Micro build as a mid-fi mono amp for listening to music on and off, but my Princeton Reverb build has taken over as my main amplifier. I've been considering gutting my Bassman Micro (which I'd already butchered by turning it in to a Trainwreck Rocket style mini-amp) and using the parts to build something actually designed more for listening to music to. It doesn't have to be particularly loud, and the build is more going to be about the best I can do cheaply. The 370AX power supply limits my output options somewhat too, and I'd rather use that than buy something. Essentially, I'm thinking of mashing together the 4S Universal Preamp, a cathode follower, and the 12AU7 power amp from the Deluxe Micro build, and pretty much keep the Bassman Micro power supply/filtering section. I read quite a few people suggesting adding a cathode follower to the 4S preamp, which is why I've added that in, and I'll probably add in a pre-amp out and switched dummy load so that I could use a more powerful power amp with it in the future. I'd seen that someone has already had a go at doing something similar with the Deluxe Micro too. This means that I'd need to buy one extra 12AU7, and two output transformers (I'm going to go with the Hammond 1750A), and I should have everything else I would need on hand. I have had a go at putting together a schematic for this idea, just showing one channel (obv. it'd be the same for left and right). Does anyone have any thoughts/suggestions? This is only my 5th build so I'm still very much learning. Thanks!
