Tamradio / TAMURA transformers standard with new look chassis below .
The 300B originally designed by Western Electric in 1933 as the 300A and in 1938 the 300B.
It was primarily used in telephony and then fitted to theatre amplifiers .
The 300B design has a magical midrange quality , reproduction of human voice is very lifelike .
We have combined the 300B now with Tamura output transformer option to give the listener the ability to hear spatial characteristics that are lucid and engaging.
The positions of singers and instruments are pin point accurate and move in harmony as they shift across the stage .
The power and punch of bass lines and leading edges of notes are pristine in their reproduction.
Strings and woodwinds are presented in full bloom , layered and textured with a beguiling sense of realism .
The toroidal power transformer is very low in spurious emissions allowing for very quiet operation combined with DC regulated heaters provide no audible hum at all, perfect for high efficiency speakers.
Tamura 20Hz -90KHz total frequency range and 20Hz - 30 KHz -1dB
Electra-Print transformer option 20Hz- 25 KHz -1dB great bass !
We are now offering new production Western Electric 300B tubes as an option .
E180F replaces E280F driver tube.
Tamradio Tamura have been in production since 1934 and winding techniques over many years have perfected the sound of these transformers we now offer.
We use Genalex 300B as standard but Elrog and Western Electric are available as options to order.
The Single Ended 2A3/6C4C is perfectly suited to full range drivers like Lowther,Feastrex,Fostex, Full Range Horns and Contrast Audio Speakers.
The Rod Coleman Constant Current Source Heater Supply ensures very quiet running free of hum.
The back to basics 6SF5 driver tube direct coupled to the 2A3 / 6C4c is a very linear tube resulting in low distortion.
This amplifier is inherently musical and lifelike in its musical portrayal .
Individual instruments are pin pointed within are large sound stage .
Performers voices have a naturalness about them which is quite beguiling .
Micro detail is a real strength of this amplifier , midrange and high frequencies blend naturally together , solid bass is there in spades .
GZ32 will be replaced with a 6BY5 rectifier tube in the new chassis.
We employ quiet running toroidal power transformers ,low in spurious emissions which contribute to a very quiet clean sounding back ground in which the music can present itself .
Tamura 20Hz -90KHz total frequency range and 25Hz - 30 KHz -1dB
Electra Print Transformer Option 20Hz- 25KHz -1dB great bass.
We have chosen TAMURA for the standard issue with this amplifier moving forward , it is a world renown brand since 1924 !
We also offer a Japanese wound Double C core Amorphous output transformer to match the earlier Tamura 5002 .
This Amplifier can be used in Triode and Ultra-linear Mode for more power .
For those wanting a little more power than a 300B then the KT88 will deliver up to 12 watts in Ultra -Linear and 8 watts in Triode.
Ultra-linear is more dynamic in its presentation providing excellent dynamics but retaining that all important tube smoothness.
In triode mode we are back listening to a cross between a 2A3 and 300B , the best of both worlds when combined with the detailed performance of the Tamura or hyper detail of Japanese Amorphous.
Tamura 25Hz -65KHz total frequency range and 25Hz - 30 KHz -1dB
