Pandora – Mono Power Amplifier
When opening Pandora’s box Greek mythology tells us to expect “Any source of great and unexpected troubles”. Now imagine you must open 2! Even more sources of trouble?
Not when those boxes of Pandora are delivered by Sasa Cokic. Each of these boxes contain one of the finest tube mono amplifiers on the market, presented to you under the name Pandora. Designed to bring you the ultimate musical experience and joy.
Beautifully hand crafted designed housing, technically based upon the Svetlana 811-10 power tubes these mono amps deliver you up to 40 Watts in pure Class A each.
Sonically the Pandora mono amplifiers present a grand palette of musical textures in the best Trafomatic fashion. Bass is tight and fast, the mid-range glorious, the high frequencies liquid and airy.
- Combination of direct coupling between stages and Interstage transformer coupling
- Implements special C-L-C anode voltage filter using Mundorf MLytic HV type electrolytic and High inductivity filter choke made by Trafomatic Audio
- Oversized , low inductivity II C core main transformers
- II C core oversized output transformers
- The output transformers are highly sectioned with harmonically sized sections, which results in a minimum leakage inductance and the best high frequency performance
- -3dB feedback
Imagings are superbly holographic and the soundstage vastly layered and wide. While sonics are stunning, they will never be in the way of the music’s embedded emotions. The Pandora mono’s are dynamic amplifiers with a firm grip on the beat to convincingly portray musical motion and faithfully capture how live music flows over time. They recover plenty of detail, provide very good articulation of vocals, produce a large sense of space and build their virtual stage on rock-solid imaging.
Pure and elegant in design, circuit minimalism with very high quality parts preserves the primal qualities of reproduced sound and opens up new dimensions for the playback experience.
The Pandora monoblocks run two drivers tubes 6N30P called also “super tube” and two direct heated triode made by Svetlana 811-10. Each amp houses an epoxy resin-potted 6kg double C-core output transformer, 10Kg main power double C- core transformer , one high inductivity filter choke and an interstage transformer for driving SV811-10 tubes all made by Trafomatic Audio
High-level line input transformer LL1592 provide phase splitting with high degree of simetry.
All tubes are with DC heating to improve signal / noise ratio .
Pandora used -3dB of NFB just in output stage ( cathode feedback )
Pandora doesn’t use capacitors in signal way .
