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.

Twinings Tea Box Preamp
Twinings Tea Box preamps are genuinely made from Twinings Tea boxes. Four fine and lightly scented teas come with the well presented box. Though the box timber is light weight and velvet lined, the adding of bituminous Al foil to the inside increases box weight and provides a RFI and EMI shielding.
No screws scar the the timber box top by the use of internal adhesive "stand offs" to mount the component boards. The two circuit boards are component-2-component wired. In a preamplifier, keeping the signal path as short as possible is essential. Only clean DC power enters the preamplifier section. With a remote power supply and valve rectification a very quite and detailed sound reproduction can be ensured. Not to mention the addition of a very cool looking timber preamplifier.
