EC-300B

A Class Single Ended 10W+10W Power Amplifier

The legendary 300B power triode has long been the first choice of many serious music listeners because of the natural, emotional presentation of amplifiers using this power tube. The 300B tube works very well in traditional circuits and this is part of the reason why this ancient triode has become so famous worldwide. We appreciate the achievements of old-fashioned single- ended 300B amplifiers, but the dream of the full potential of 300B for musical reproduction has only come true with the creation of the EC-300B amplifier.

In the EC-300B, 300B tube is special adaptation of our proprietary IITC interstage transformer coupling circuit. Our design is carefully tailored to furnish ideal drive conditions for the output tube, opening the door to dramatic new levels of low-end articulation and dynamic excitement for single-ended 300B amplifiers. The ample 10 watt output of the EC-300B provides full-bodied musical reproduction that you will appreciate for a long, long time.

The result of our intensive research, the EC-300B, is a completely modern amplifier dedicated to the timeless quest for musical enjoyment.

Features

-An Adaptation of IITC circuit concept featuring a unique configuration
which cancels DC magnetization in the interstage transformer for
outstanding bass performance and rich musical reproduction.

-All direct-coupled circuitry. We avoid coupling capacitors to ensure
maximum purity of reproduction.

-The 300B heaters are supplied from a well filtered DC source to
minimize hum and noise.

-The 10mm thick chassis is NC machined from solid aluminum and
finished in a satiny champagne-gold finish.

-The specially-designed transformers used in WAVAC Audio Lab. amplifiers are
custom-wound to the highest standards by TANGO, the most
renowned transformer manufacturer in Japan.

-All tube sockets are machined out of solid Teflon, fitted with gold
plated phosphor bronze contacts and mounted on elastomeric
vibration insulators.

-Gold-plated speaker jacks which will accommodate heavy audiophile
speaker cables are mounted on the top of the amplifier for easy
access.

-Reduction of noise caused by electric power supply is realized by
a power line input filter.

-A perforated aluminum bottom plate provides effective cooling for long
component life.

-An attractive laboratory glass canopy suspended on elastomer
supports is provided the output tubes.

-The input tube is a triode-wired Western Electric 435A, a superb
small-signal device designed to meet the highest standards of
performance and reliability in vital telecommunication applications.
