- The “Mandatory Project”, intended to prevent future projects from “going up in smoke.”
- Also included: tips on setting up a convenient workspace.
- Acoustic Preamps – save hundreds of dollars with these simple projects that will enable you to use your existing amplifier with an acoustic instrument.
- Experimenter’s Power Supply – a dedicated bench supply to power any tube-based project. Supplies enough power for any preamp up to six 12AX7s, or for a small 15W tube amp.
- Electric Guitar Preamp – using two 12AX7s, includes a clean and a dirty channel, with separate EQ for each.
- Bass Preamps – with an explanation of what is unique to a tube preamp for bass, and how modern techniques can improve tonal flexibility.
- Small Tube Power Amp – build a 10W-15W power amp and learn the principles of tube amplification.
- Class-A Solid-State Power Amp – a simple circuit designed for hi-fi is adapted to guitar use.
- Reverb Unit – build a stand-alone reverb using readily available parts for a classic tube sound.
- Wide-Range Tremolo Circuit – can be used as a pedal or incorporated into an existing amp to free up a tube.
The intended reader should have experience with a soldering iron and multimeter. The ability to read a schematic diagram is helpful but not essential.
Note: “Tonnes” are metric “tons”!
