Stereo Vacuum Tube Amplifiers

Tube Power Amplifier

         The photograph shows a 'one tuber' - a single

ended, stereo, power amplifier utilizing just one

'spud' per channel.  Designed & produced 

exclusively within the United Kingdom by 

accomplished engineers, this model, crafted to 

order, is of the type in which just three components 

lie in series with the audio signal path to attain near 

optimum musical reproduction.  The output

transformers * (also designed in-house) are of  premium grade, well proportioned & elegantly interleaved

to secure adequate magnetic coupling & the desired response.  The amplifier can deliver an average 

5W ** into a pair of 8 ohm loudspeakers & has an input sensitivity of 3Vrms.  The design is such that the 

second harmonic component is promoted whilst higher orders are attenuated; the overall characteristic

sound reproduced has been likened to that which was ubiquitous during the era of vintage wireless.


    -     Tubes:  EL84 Output Pentodes.

    -     Zin:  > 150,000 ohms.

    -     Feedback:  0dB  (decreasing distortion complexity).

    -     Tube Biasing Method:  Self.

    -     Output Transformer Lp:  24H @ 30Hz. 

    -     D. C. Fuse:  250mA, anti-surge.

    -     Power Consumption:  55 Watts. 

    -     Power Bandwidth (DIN 45-500):  2.5Wav + 2.5Wav over 30Hz to 16KHz into 8 ohm loads with                                                                      3Vrms input signals. 


    -     Recommended Loudspeaker Sensitivity:  93dB - 98dB.  Never operate the unit without                                                                                                                      loudspeakers connected.


    -     Unit dimensions:  W 14 3/4" (375mm),  D 4" (102mm),  H 4 3/4" (121mm) + 20mm Glass Plinth. 

     -      Weight:  3.5Kg (Approx.)

          The amplifier comes complete with fitted, protective base-plate & cover.  The electronic

component parts of the assembly are connected by method of point-to-point & the overall stylish, 'in-line'

construction facilitates bookshelf (or other practical) placement.  The unit sits smartly on its own

modish, smoky grey, toughened glass plinth consonant with contemporary furnishings.   If desired, it 

can be driven directly by the audio output of a laptop computer.



          HIGH VOLTAGE WARNING!   Under no circumstances should the assembly be 

dismantled or any component part removed.  In the event of a problem, disconnect from the

power source & 'Contact' us or a qualified technician.



          The 5-pin DIN audio socket is preferred over RCA for earthing considerations.

          The 2-pin DIN loudspeaker sockets are favoured over other options for their practical 

convenience, & although somewhat restrictive in terms of accommodating sizeable cable gauges, it 

should be noted that in our experience it is the quality of copper conductor that determines the end 

result, not its mass.  A 10m length of 1mm diameter, high grade copper conductor is adequate to 

deliver good audio fidelity - the degree of exactness to which recorded music is reproduced.


          We offer the option of anodized blue chassis with this model (view 'Photo Gallery') & 4 ohm 

output impedance; we also produce a 'Tetrode Tube Amp' version.  The transformer cover & base plate 

are black.


          A one year warranty is given covering any production defects.  As a consumer you are entitled to

a full refund should the amplifier fail independently within thirty days of receipt; moreover if not 

completely satisfied you may return your amplifier within fourteen days of receipt for a full refund in 

accordance with the 'Distance Selling Regulations'.  The assembly must arrive back to us in pristine 

condition & please note, we do not refund the return carriage.


          We sell this product almost exclusively to U. K. residents - we do not export other than to a 

limited number of selected destinations.
