Egg-Shell - vacuum tube audio amplifiers by Encore Seven

ENCORE 7 is the small artisan manufacturer from Poland offering only just a few products. All of them are basically the same – An amplifier, but it is offered to customers as variation of three models with three possible finishes available to complete that complex offer ! They also supply revolutionary guitar power amp build on the same sonic principles as their hi end products range.

On company’s future achievement list are now : Separated Preamp – Power Amp combo as well as their Mono block version. Matching Phono stage had been now complied and launched. Please find more information about bellow the amps info.

NEW ! …and innovative remote control sphere comes now to match Egg Shell !

Amplifier itself not only sounds good , but also looks very stylish. Unique chassis had been designed to fulfill not only esthetic demands, but also first of all, to meet circuit demands for the best sonic execution. Neither to say both targets had been completed and this wonderful amp is nothing but the shining little star. With lovely balance between pure ART DECO  proportions and V6 engine like layout for all vacuum tubes included it is A LOOKER and THE PERFORMER at the same time. It is also WOMEN”S APPLE IN AN EYE!

Egg-Shell tube amplifier

PRESTIGE RANGE WITH EL34 POWER TUBE

Please have a closer look at complete Egg-Shell amplifiers line  in our offer to find more about. Two of them are Triode circuit employed EL 34 Pentode based amps.

The amplifier marked with the  number 15 has 15W RMS power per channel and operates in class A. The second model has the power of 9W RMS per channel and it also operates in class A. It additionally differs from the more powerful brother by having its power supply system based on vacuum tube rectification. Other way they both using same output tube.

CLASSIC RANGE - ONLY WITH EL34 POWER TUBE

Egg Shell Classic range is sporting exactly the same circuit as their Prestige amps but enclosure is simplified to keep the price down. Other way they are sharing the same voicing. The same specifications apply as above. A an example bellow there is a picture showing model 9WST in Classic implementation. The model name is Classic 9WLT.

Important note:

Classic range can not be supplied with Egg Shell remote due to lack of space to accommodate giro receiver module inside.
