loudspeakers and/or the preamplifier!
When powering off the system, always switch off the power amplifier first, then switch
off the other components of the setup, observing a delay of at least 30 seconds!
Keep the original crate and the tube protection case for later use. They have been
specifically designed for safe transport under rough conditions! Shipping the amplifier in
inadequate packaging will result in catastrophic damages!

•Vacuum Tube MOSFET Hybrid Power Amplifier offering 30 40 or 50 watts of
output power into a 8 6 or 4 ohm loudspeaker load respectively utilizing two
vacuum tubes (6J5GT or 7A4 and 1x12HG7).
•Ultimate sonic excellence on par with no-compromise all-tube single-ended
triode amplifiers without involving exotic and costly power tubes.
•Excellent driving capabilities for critical loudspeaker loads due to very low output
impedance (high damping factor).
•Unique zero-feedback EHT schematic: single-ended triode gain stage followed by
a unity-gain vacuum tube buffer driving a unity-gain single-ended MOSFET
output stage operated (class-A) at high idle current.
•Total avoidance of sound degrading protection circuitry.
•On-the-fly selectable gain via 6-position rotary switch on the rear panel 2 of
which positions are assigned with subtle bass boost presets.
•High grade electrolytic capacitors made in Germany in the power supply.
•Low noise dual-coil C-Core mains transformer made in-house for 230Vac (115Vac
via jumper setting) 100Vac (Japan) 120Vac (USA Canada) 220Vac (South Korea
China Thailand Indonesia) 240Vac (UK) or 245 Vac (Australia).
•Full hand construction point-to-point wiring throughout.
•Nonmagnetic aluminum casework front and rear panel with anodized printing
powder-coated lids.
•Dimensions 434x454x184 mm 184=20 (feet)+134+30 (tubes over case)
•454=434+20 (speaker binding posts) weight 15Kg.
•Dimensions of the shipping crate: 650 x 650 x 350 mm.
