EAT reputably manufacture some of the world’s best 300B, KT88, ECC803 & EC88 audio tubes.
The tubes are precision manufactured in a factory (a portion of the old Tesla tube factory) in Prague, Czech Republic which cranks out the parts and materials, and then final assembly and listening sessions with reference source materials take place in Switzerland. As a result of the very high focus on fine tolerances, EAT can claim a life expectancy that is about 50% longer than normal valves.
EAT KT88 diamond, gold pin audio valve
The EAT KT88 tube is in a league of its own. This KT88 tube is available in factory-matched pairs & quartets. Its construction features include black plates, black metal base, and gold pins.
The EAT KT88 has an designed maximum anode dissipation rating of 35W and is recommended for use in the output stage of an a.f. amplifier. Two valves in class AB1 give a continuous output of up to 100W. The KT88 is also suitable for use as a series valve in stabilized power supply.
EAT 300B Valves
These tubes appear to be designed from the ground up. They are better at dynamics and sonic neutrality than vintage (or reissue vintage) tubes while remaining ultra smooth and state-of-the-art detailed. This is 21st Century tube sound for the world’s best phono and SACD reproduction. You cannot go wrong running EAT 300Bs in any application.
EAT ECC88 Cool Valve Diamond reference audio valve fitted with Cool Damper
Many people prefer the sound of EAT ECC88 triodes tubes for their "soft" saturation characteristics which can be quite pleasing to the ear!
The ECC88 Double Triode valve comes with a Cool Damper pre fitted which offers a more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.
Equivlent tubes: E88C / 6DL4 / 6T
EAT ECC803 Cool Valve Diamond reference audio valve fitted with Cool Damper
The ECC803 Double Triode valve comes with a Cool Damper pre fitted which offers a more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.
All EAT Cool Valve ECC803S's are required to pass through rigorous testing to meet EAT's high standards. As a result of this selective process, all ECC803S's are matched to very similar specifications.
Equivlent tubes: 12AX7 / 5751 / 7025 / 12AD7 / 12DT7 / 7729 / 6681 / 7058
EAT Cool Damper for audio valves
The Newest Assault on Tube Micro-Vibration:
The EAT Cool Tube Dampers will Improve the Sound of any Tube Gear.
The Cool Damper uses an ingenious and extremely effective vibration control system to effectively reduce tube vibration; this same system allows the Cool Damper to accommodate a large variety of input tubes with a range of diameters from 19.5 to 22 mm.
