Finally finished this JJ12AU7 preamp - SRPP. Finish is blue hammer tone on a Hammond wood cheek chassis. The cct. is constructed on a turret brd. with metal film resistors and Russian PIO caps. Pot is Alps blue velvet with 4oz solid brass gold plated knob. External PS supplies 260V HT and DC filament current. Two selectable inputs. Sound is very fast and snappy with good bass.
Retro thermionic audio harks back to the golden age of sound, utilizing vacuum tubes and thermionic valves to craft warm, rich tones. These analog components, reminiscent of mid-20th century technology, impart a distinct character to audio signals. Engineers embrace the harmonic saturation yielding vintage vibes sought after by audiophiles and music lovers. This process involves designing circuits with artistic and aesthetic intuition.
