No, we do not use ultra-linear/triode operation – Inferior for High End Audio

Ultra-linear electronic circuits are those used to couple a tetrode/triode or pentode vacuum-tube to a load (e.g. to a loudspeaker).

‘Ultra-linear’ is also know as ‘distributed loading’; a circuit technique patented by Alan Blumlein in 1937. Ultra-Linear “distributed loading” was intended for guitar amps, etc.

• In pentode or triode, in which the screen-grid is connected to a stable DC voltage so there are no signal variations on the screen-grid (i.e. the screen-grid has 0% of the plate’s output signal impressed on it), or

• In triode, in which the screen-grid is connected to the plate (i.e. the screen-grid has 100% of the plate’s output signal voltage impressed on it), or

• a blend of triode and pentode, in which the screen-grid has a percentage (between 0% and 100%) of the plate’s output signal impressed on it. This is the basis of the Ultra-Linear “distributed load circuit” and is seen as a form of feedback, which alters the behavior of the electron stream passing from cathode to anode.

Ultra-linear/Triode introduces negative feedback, which squashes and compresses the sonic performance.

So the Pentode/Triode operation will yield a vastly superior response and more of a “tactile” or SET sound, more of a three dimensional sonic signature. Quite Superior!

Ayon Scorpio II Tube Integrated Amp -Pure Class A

The Legacy models, previous models to the New Ayon Scorpio II proved to be the best selling vacuum tube integrated amps, globally!

The Ayon Orion, Ayon Orion II, Orion III and the really super nice Ayon Scorpio with the crazy good intelligent auto bias and vacuum tube monitoring system, which not only auto biases the vacuum tubes, but will also detect and notify the owner that a vacuum tube is misbehaving and should be replaced, were the best sellers globally.

No other high end audio vacuum tube manufacturer has this type of really helpful feature that prevents damage to the amplifier from a spitty tube!

Now Ayon introduces their New Ayon Scorpio II, Manufactured in the EU –

WoW – what a beautiful sounding amp! No other vacuum tube amplifier in this price category touts, Pure Class A in Pentode & Triode mode.

No Ultralinear operation, you do not want ultralinear operation, high distortion, high power output which looks good on paper, but the amp is driven hard, not as reliable as well, not to mention the sound is inferior. Ok all owners that have an ultralinear amp, please don’t email me!

The Ayon Scorpio II also has the auto bias, plus the aforementioned crazy good intelligent vacuum tube monitoring system. Makes owning a vacuum tube amplifier a real pleasure.

So what does the Ayon Scorpio II integrated sound like. Amazing – refined, organic, zero feed back – no noise, three dimensional, low damping makes for a fast tight bass, warm fluid mids, super smooth highs. Built like a tank and elegant. Superb build – what you will always get from the folks in Austria, Germany – where the amp is made.

Vacuum Tubes

The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. This is not only the decision between good and bad tubes but finally the interaction of the different types of tubes and their combination that are used in the various Ayon amplifiers.

Signal Path

We believe that the simplest circuits work best together with the shortest signal path. The shorter the signal path is, the less possibility of sonic degradation from various sources, including the wire itself. Even on the circuit boards, the copper traces are kept to a very minimum length. The completely redesigned circuit board provides a more straightforward and direct approach to the signal paths.

  • Logical sequenced soft-start power up for extended tube life
  • Power tube and electronic protection circuit system
  • 0dB negative feedback  (of any kind)
  • Ultra short signal path
  • Simplest direct circuit path for purest musical sound and high reliability
  • No solid state devices in the signal path
  • High current and low impedance design that operates the tubes at their best level of performance
  • Minimal discrete wiring for optimum signal propagation
  • Automatic and manual bias adjustment
  • No followers or buffers in the signal path
  • Quality parts throughout
  • Selector switch engages relays located near RCA jacks to switch all inputs

Power Supply

The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformers, chokes and filters provide total isolation between the input and output stages which makes this a pure power source. We also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.

  • Low noise –insulated power transformers
  • Power transformer is encased, excellent damped and RFI/EMI shielded
  • Innovative power supply provides a high speed energy delivery on transients
  • Choke filtered power supply
  • Separate and isolated power supplies over each stage of amplification
  • High current filament-regulator for pre and driver tubes
  • Regulated DC filament supplies with soft start
  • AC power line filter to avoid noise and hash from entering into the unit
  • Current in-rush limiting
  • Auto sequencing – Power on cycle completes in 1 minute

Output Transformer

The super-wide bandwidth output transformer’s major strength is that it can deliver the current in the bass, while at the same time maintaining the speed in the high frequencies, dramatically improving the square wave response of the amplifier. The effect is a much more natural and relaxed sound with much better clarity, resolution and fluidity.

  • Super-wide bandwidth high performance output transformer
  • High efficiency with low insertion loss for optimal current and voltage transfer
  • Multiple tight layering and coupling for extended frequency response
  • Output transformers are sealed with an anti-resonance compound material


The type of parts used therefore must have a synergistic relationship to the circuit they are placed in. It is this relationship of which type of part to use where, that ranks our products apart from the masses.

  • Selected, quality passive components used in all applications
  • High speed & high quality audiophile grade coupling capacitors
  • Special tube sockets with beryllium- copper spring pins, custom made by Ayon
