DIY Preamp recommendations

Just finished refurbishing my dad's pre/power amps and am hooked 🙂

For my next project I would like to build a pre/power amp combo, starting with a preamp. There are so many options that I am getting a bit lost. Can anyone recommend a preamp build with the following criteria:

1. transistor-based (not valve) and class A, obviously
2. no phono stage, tape monitors etc
3. bass and treble controls
4. preferably sonically compatible with a good class A/B power amp
5. good/high quality

Many thanks!
