Aficionado

 

 

Now with tertiary winding!* Eddie Current Aficionado is a vacuum tube headphone/ speaker amplifier amp. The amp’s unique audio circuit, combined with a passive LC filter power supply delivers the Holy Grail of a high fidelity, a sound stage designed specifically to maximize the 2A3 electron cloud. On a quest to bring back classic tube-driven audio, the Aficionado is cap coupled through an old school Russian military toxic oil, paper, and aluminum foil capacitor. Output transformers are machine wound by CineMag Transformer. End result, an updated modern version of classic American audio design!

* To use the tertiary or not–this is the question. Back in the day Macintosh Labs made the most sought after Hi Fi tube amplifiers. If you were in the hobby you wanted one, like a high school kid dreaming of owning a Corvette. Sadly, I never owned either but pored over the Mac schematics. They had a patent on using a tertiary winding in their output transformers. It reduced distortion, and increased bandwidth. Years later when the patent ran ou,t Audio Precision used it in their test equipment transformers to reduce distortion to ridiculously low numbers. This is the same idea used in the Eddie Current transformers with tertiary. This is a compact winding close to the transformer core put into a feedback circuit. Like the Macintosh amps it reduces distortion, and increases bandwidth. The feedback is used very minimally as not to disturb the sound stage. For example in solid-state amps feed back is typically 20 to 30 dB. This guarantees compression, and a flat sterile sound. In the SE amps we build only 1.75dB is used and the sound becomes clear, and present. The same amp without the tertiary connected will sound good, but more euphonic, typical of SE amps from the old days to present.
