Hello DIY'ers, first time poster here...

I'm a life long audiophile, and amateur at electronics. I know how to troubleshoot circuits, calculate voltage drops, stuff like that and I've actually restored some tube gear. However, I'm trying to broaden my horizons and start figuring out how to build stuff.

I have an ambitious project in mind - I want to build (pieces at a time) a basic preamp. I want to start by learning to make DAC's, then hopefully how to switch digital and analog inputs with op amps (read that from another DIY'er), learn how to make non-pot-based volume and tone controls (hopefully with MOSFETs), etc. Ideally I want to build from scratch a full tube receiver all from scratch, with built in digital inputs and raspberry pi for network streaming. (Like I said, ambitious)

The brick wall I'm hitting is that I have never been able to figure out circuits to the full extent. I look at data sheets for certain IC's and it starts looking like gibberish. I understand the resistors and capacitors (and to a limited ability what they do and how) but then they start throwing out abbreviations I don't have a clue about and logic stuff. This has really hindered me in learning how to build complex circuits.

Can anybody recommend a good read for me? Hopefully e-book and free? Something centered in audio circuitry would be nice but anything that can teach me how to put part A and B together (and make them work) would be a god-send.

Thank you all

There are lots of good .pdfs out there.
Look at the RCA manual RC-30. It's a good book but definitely not all encompassing. It's a tube manual that has circuits at the end and some decent explanation at the beginning.
