E.A.T. E-Glo FB Phono-Preamplifier

E-Glo FB: Fully symmetrical high-end tube phono preamplifier of the reference class

With the EAT E-Glo FB (Fully Balanced), analog music reproduction achieves an exceptional level of precision. Building on the success of the original E-Glo and the E-Glo 2, this consistently refined phono stage employs a fully discrete, pure tube design without any semiconductors in the signal path. Fully balanced throughout, from the input through the amplifier and equalizer stages to the subsonic filter and output, this preamplifier operates with true balanced tube amplification – far removed from simple tube buffers or unbalanced circuit designs.

Eight select tubes for maximum sound quality and flexibility

At the heart of the circuit is a sophisticated array of four ECC83 and four ECC88 tubes. Compared to its predecessor, two additional ECC88 tubes enable uncompromisingly balanced operation across all amplification stages. Music lovers benefit not only from the easy availability of replacement tubes, but also from the option of "tube rolling": By selectively using premium tubes, the sonic signature can be individually tailored to suit one's own high-end system.

Uncompromising signal purity thanks to balanced XLR inputs and Lundahl transformers

For optimal compatibility with moving-coil cartridges, the EAT E-Glo FB integrates a high-quality Lundahl transformer (type LL1932) with an amorphous core. Together with a basic gain of 45 dB, this effortlessly and with minimal noise amplifies even the quietest MC signals to the desired level. Equalization is achieved via a split, fully passive RIAA circuit – deliberately without sound-degrading global negative feedback.

Thanks to the new balanced XLR inputs for MC cartridges and specially modified balanced MM cartridges, external interference is effectively suppressed. The result is an unprecedentedly low noise floor and pristine detail that brings out even the finest nuances in the record groove. (Note: Conventional unbalanced MM cartridges are not suitable for balanced XLR operation due to their internal grounding.)

Audiophile-grade components for maximum stability

The E-Glo FB uses only selected top-class components inside:

Semi-crystalline hydrocarbon polypropylene film capacitors: These replace the previous MKP capacitors in the signal path and in the passive RIAA stage and impress with an extremely low loss factor, highest impulse power handling and almost perfect temperature and frequency stability.

Mundorf components: Highly acclaimed Mundorf output capacitors and Teflon-insulated Mundorf connectors guarantee lossless signal transmission for decades.

External power supply for absolute interference-free operation

To keep electromagnetic interference away from the sensitive amplifier electronics, the EAT E-Glo FB is powered by a separate external power supply. This is connected via a special 9-pin connector reminiscent of the legendary Cello Palette preamplifier. Inside the visually appealing, all-aluminum housing, a custom-made toroidal transformer with double shielding between the primary and secondary windings acts as an effective mains filter against high-frequency interference (RFI). Special diodes with noise-reducing resistors, high-quality electrolytic capacitors, and a voltage regulator with a capacitance multiplier and FET power transistor ensure an absolutely stable power supply.

Timeless elegance and comfortable operation

Visually and tactilely, the phono preamplifier impresses with its solidly constructed, all-aluminum chassis, available in elegant silver or timeless black. All cartridge adjustment settings are conveniently accessible via clearly arranged rows of switches on the front panel – there's no need to open the housing at all. A dimmable and color-adjustable LED backlight stylishly illuminates the glowing tubes.
