RE: SET 45

Hi lugnut,
Yes, if you choose a good schematic, decent parts, have competent build skills and do your research, I'd be surprised if you could not exceed many commercial offerings.
Use transformers designed for SE, preferably with a slightly high primary load (that would be ~5K for a 45 run at common operating points).
As for specific designs, it is a case of "ask ten people, get ten different answers". Peoples' sonic preferences, experiences, systems and biases are different. Some might suggest to build a kit first; that can work, but understand you are learning the way someone else wants you to build, which is different to doing research yourself. Still, it can be a fast-path to some success.
I won't tell you what to do - we are each different - but I built something that was decently well documented, generally well-liked, and relatively easy to build and trouble shoot. I researched build techniques and grounding extensively. I had no critical issues with the build (just some slightly high voltages due to high line voltage), it is quieter than most, robust and it sounds nice to me. I could easily improve the layout, but it is better than many commercial amps I have seen the internals of. I do not regret building it for a second - experience matters.
Now that I have my first build completed, which serves as a baseline, I will move on to something more exotic or take the path less traveled... but I am not in rush.
Feel free to shoot me an email if you have any further questions - maybe I will be able to offer you some advice.
Regards,
91.
