diy SET KT88/6550/EL34 power amp, several pairs of diy speakers
jazz, classical, 70's rock, blues, etc.
I recently retired after 31 years as a mechanical engineer.
I started building speakers over 25 years ago, with a special interest in series crossovers. About 10 years ago, I became interested in tube amplifiers, especially Single-Ended Triodes. After building a power amp for my bookshelf speakers, a dedicated headphone amp project was next on the list.
