EAT ECC88

The EAT ECC88 is a special quality double triode. The tube satisfi es the specifi cations in accordance with MIL-E-1/1J168 (NAVY) from 18.6.1958.

Tight tolerances: In these tubes the tolerance of electrical ratings are reduced in comparision with standard tubes.

Vibration and shock proof: The tube withstands accelerationns of 2,5 g at 50Hz for lenghty periods and momentary shocks of 500g for short periods.

Cathode free from Interface: The cathode establishes no interface even in case where the heated tube is operated without plate current over lenghty periods.

COOL VALVE ECC 803S

The Cool Valve ECC 803S is the finest twin triode with separate cathodes available in today’s market. Double triode means the valve is built with two totally independent triode systems.

The most demanding tube for both sound and build quality is Telefunken ECC 803S. This original tube can only be sourced from old inventories and not reliable sources offering no warranty period. There is the risk of forgeries, functionless valves or overpriced goods.

We tried to fi nd a way to make a better product for high requirements of exclusive amplifi ers.

EAT has set a high standard by trying all existing ECC 803S by defi ning sophisticated selection methods to get only the very best to our demanding customers.

The selection procedure uses several measurements. All measurements are performed after a long burn-in procedure and thermal stabilization of its parameters. Only a few valves pass the Selection process and even fewer pass the strict Diamond selection.

The inseparable part of the Cool Valve ECC 803S is the EAT Cool Damper. EAT developed a special high temperature glue to fi x the damper to the valve glass envelope. This glue is designed to transform vibration energy into thermal energy, which is then dissipated as heat. The Cool Damper is a truly effective vibration & micro-phonic absorbing device.

COOL DAMPER by EAT

MULTIFUNCTIONAL VALVE RING

The Cool Damper is a radical new device for the tube accessory industry from EAT – EuroAudioTeam. This beautifully crafted audio product offers much more than simply adding a new styling twist to your valves by surrounding them in new, fashionable colours. It brings exceptional acoustic performance and function to your system by delivering sound that redefines the tube dampening category

Carefully chosen materials for our Cool Damper device allows using it as a truly effective vibration-consuming damper. This results in reduced distortion from the tube circuit, as well as vastly reducing the tendency of most vacuum tubes to act in a microphonic manner. In addition, the sound from a component utilizing Cool Dampers can be heard to have more controlled and deeper bass, a cleaner sound stage, crisper and greater dynamic range, and better focus of the entire sound field.

The Cool Damper also reduces the operating temperature of the glass envelope of an electron tube by about 10 %, which of course acts to appreciably extend the lifetime of the tubes.

The Cool Damper is a result of many years of rigorous research and development. This high-fidelity, consumerfriendly product is easy to install, and fabulously simple in design. We found, from all tested materials, that the most suitable is a relatively soft aluminum extrusion coated with a special blended mix of Teflon and Carbon composite PTFE. The precise shapes of the EAT Cool Dampers are finished with long-lasting anodic oxidation colours. This makes these cooling rings an aesthetically attractive, as well as functional, accessory for your valued vacuum tube equipment.

For flexible and easily detachable contact of the aluminium body to the sometimes erratic cylindrical surfaces of various tubes, we use six special carbon-teflon composite stripes (V profile). Appropriate design and materials of the Cool Dampers compensate for the naturally resonant tendencies of both glass and aluminium, and work to transform active vibrational energy into thermal energy, which is then dissipated as heat radiation.

Tube dampers in one form or another have been around for many years, but these from EAT are so much more effective than any previous efforts that they deserve to be auditioned on their own merit.

KT88 DIAMOND

BEAM TETRODE EAT KT88 DIAMOND

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.
