About this guide
Building a tube amp from a kit gets you real point-to-point tube sound at a fraction of a finished boutique amp’s price — and the hobby has enough well-documented kits now that a first-timer doesn’t have to guess. These range from beginner headphone amps to classic stereo speaker-amp rebuilds, so pick based on what you’re actually driving.

Buying tips
- Decide headphone amp vs. speaker amp first — the Bottlehead Crack and AE1 solve very different problems than the ST-70 or TU-8600S.
- Budget separately for a chassis/enclosure if you buy a board-only kit like the Reland Sun.
- First-time builders report far fewer headaches with Elekit’s pre-matched kits than with looser hobbyist boards.
