Descrierea produsului
The EX888 is a tubes amplifier using KT88 power tubes and 12AX7/12AU7
for pre-amplification. We wanted to achieve with the EX-888 an amplifier
with an exceptional sound that honours the legend of tubes but also
benefiting from a reserve of power that allows easy association with the
majority of speakers in the market. To achieve our goals, we used a
proven pattern but with some unpublished parts (including a so-called
anode follower), which allowed us to reconcile a low rate of reaction
against (ensuring maximum power) and a very low level of distortion
(less than 1% with a gradient odd harmonics characteristic of
achievements tubes). HIGHLIGHTSPre-outOptional board slotMassive continuous power of 500VA transformer MORE... Power supplyIt
is based on a very high quality impregnated EI transformer capable of
delivering a continuous power of 550VA. The diodes used in the rectifier
bridge are broadband-like to ensure a continuous tension as pure as
possible. Finally the filter is achieved by an innovative structure
called CLC ie the equivalent of a third order filter for a perfect
smoothing of the output voltage. Output transformerThe winding of
the output transformer uses a structure to achieve perfect symmetry
output stages and the same minimal distortion. They use a deoxygenated
copper wire. They are very generously sized to pass the entire dynamics
of the output stage. They are wound in 3 and 6 (normed 4 and 8)
whereas the trend (long ago) prevailing in speaker manufacturers. ComponentsThe volume knob is a motorized with APLS potentiometer. Capacitors links are aluminum insulated polypropylene sheet. They come from renowned manufacturer SOLEN. The resistors areall high power. Double side soldering. The circuit is printed on epoxy and 70 microns thick.
