VALVE (Tube if you live in the fringes) GUITAR AMPLIFIERS ARCHITECTURAL SPECIFICATION
 
    Single channel all valve amplifier with high and low gain inputs, with gain, bass, middle, treble, volume controls.  
    Valve complement to be 2 x ECC83, 1 x ECC81, 2 x 6V6, EL34, 6L6 or KT88 - dependent on model.  
    To be available in 18 Watt, 50 Watt and 75 Watt versions  
   

All components used to be carefully chosen and more than adequately rated for best reliability and performance. And I mean this..

 
    Aluminium chassis for light weight and period low magnetic interaction.  
    Power transformer to be core sheilded toroid for maximum power/weight ratio and low noise performance.  
    Output transformer to be English made, purpose designed, flash tested to 4kV. To support 4/8/16 Ohm speaker loads.  
    Circuit design to be traditional with my own optimised values. NO presence control. NO effects loop. NO drive channel s**t.  
    Power supply to use solid state rectifiers. The advantage over using a valve rectifier is too great to ignore, both in engineering and playability terms. The more energy in the power supply the better...  
    Custom made turret board construction for easy servicing, and all IO connectors to be Gold plated  
    Build standard to be as impeccable as I can make it.. (See picture below)  
   

Case to constructed from 12mm Birch plywood for strength and lightness, with choice of coverings, styles, and pipings. Style: All credit to Lyndon Laney and Jim Marshall for this one - this is a perfect and acceptable format. And it looks great. Size: 8" x 22" x 8" (HWD). Weight: approx 10Kg.

"This is simply the most beautiful sounding valve amp I have ever heard. Its warm big sound compares favourably with the vintage amps of the 1940's and 50's but with a much higher output suitable for today's musical situations. It is very light and compact weighing in at only 19 pounds. Being completely hand-assembled and wired, it is not cheap, but why would you ever need to buy another amp again". - Roy Sainsbury

"I am lucky enough to own both the Ameson RS 120 and the Ameson RS Tube 50 amps and both are superb. I have just completed recording a CD with trumpet great Bruce Adams and the engineers at the studio were absolutely bowled over by the sound of the amp. Please feel free to quote me" - Tony Marshall (Tony works with many world class jazz musicians such as Warren Vache, Scott Hamilton, Kenny Baker, etc. His brilliant new recording with Bruce Adams is now on release.)
