Nickel Permalloy 50 & Pure Silver Windings for Classic Single Ended Tube Amplifiers
Single ended 300b 8-10 watts natural timber or black finish.
Seen here with Hashimoto transformers or Tamura .
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 very high quality output transformer options ( refer pricing page ) to give the listener the ability to hear spatial characteristics that are lucid and engaging.
A warm and very smooth character.
The positions of singers and instruments are pin point accurate and move in harmony as they shift across the stage.
Full 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 aided by top of the range of Silver foil coupling capacitors.
The toroidal power transformer is very low in spurious emissions allowing for very quiet operation combined with Coleman DC regulated heaters provide no audible hum at all, perfect for high efficiency speakers.
Tube rectified .
A number output transformer choices outlined under bespoke tab .
We are now offering new production Western Electric 300B tubes as an option as well as an integrated version with dual input / Volume control.
7N7/ 6SN7 driver tube .
Standard Frequency Response 10Hz - 80 KHz -2dB
Distortion @ 1Watt: <0.1% No Feedback
Sensitivity: Variable >500 mV Full output with 7N7
Noise: < (CCIR) – 90 db
Please refer to Pricing TAB for output transformer options .
Suitable high efficiency speakers for the SE 300 B
High efficiency speakers including Horns or full range drivers including, Fostex , vintage Tannoy's , Goodmans ,Corals and Lowthers .
Single Ended 2A3/6a3 Black or birch finish .
The Single Ended 2A3/6C4C is perfectly suited to full range drivers like WHT range of speakers or Lowther,Feastrex,Fostex, & Full Range Horns.
Now available with Nickel Permalloy 50 output transformers , simply the best.
This amplifier is inherently musical and lifelike in its musical portrayal .
Individual instruments are pin pointed within are large sound and open stage .
Performers voices have a naturalness about them which is quite beguiling .
Micro detail is a real strength of this amplifier , a warm full midrange and extended high frequencies blend naturally together , solid bass is there in spades .
We tend to run our tubes at lower DC standing current and higher voltage , this lessens the current load on the transformer iron allowing for lower distortion and higher power .
A 6E5P in triode mode and the original DC coupled 6SF5 are the current issue choices .
We employ quiet running toroidal power transformers ,low in spurious emissions which contribute to a very clean sounding back ground in which the music can present itself .
A GZ 32 rectifier tube or 6BY5.
Standard Frequency Response 10Hz -80 KHz -2dB
Distortion @ 1Watt: <0.1% No Feedback
Sensitivity: Variable >1.2V Full output
Noise: < (CCIR) – 90 db
Other Bespoke output transformers are optional on the pricing page .
All output transformers are chosen from the best of the USA and Japanese manufactures.
Very low noise Toroidal power transformers are in all our amplifiers .

Worlds first commercial release SE45 pure Silver wired Nickel Perma 50 large core ,C3g and EZ81.
This Amplifier is a stunner when it comes to clarity and correct timbre of musical reproduction .
Techniques used in the winding of this output transformer, driver tube , Silver Foil capacitors and hum cancelling circuit have resulted in something very special indeed
Custom wound Nickel Permalloy 50 transformers are second to none .
We offer copper windings on the Permalloy 50 output transformer as standard and pure silver is also available if you are heading towards audio perfection.
The quality of tonal accuracy produced by this amplifier is stunning with copper windings and with silver windings unparalleled in the world.
The Worlds first commercial release of Nickel Perma 50 , SE45 combined with premium parts including Shinkoh Tantalum Resistors , Silver Foil capacitors and silver hook up wire take this design into the very highest echelons of audio reproduction.
AN Ongaku use Nickel Perma 50 Silver as does this ultra high end product but with the absolute Clarity of a 45 tube not a large 211 high impedance transmitting tube lacking in bass .
Hand built point to point wiring and convenient mA meter to measure output tube performance and bias .
Tube rectification on all amplifiers and Hashimoto DC smoothing chokes on the mono blocks .
Custom wound power supplies from the same source as Aries Cerat .
Nickel Permalloy 45 , 5Hz ～ 60 KHz -2dB
