Thrax Heros mk2 - 100W class A mono power amplifier
Product details
Heros is a very unusual hybrid transformer loaded amplifier marrying old concepts with the latest technology. The numerous benefits from using an output transformer are usually ignored mostly due to cost reasons.
Yet when done correctly the result speaks for itself.

100W Class A power output
Based on a push-pull output stage but modified with our design concepts and experience it features a tube input stage providing the necessary voltage amplification. Followed by transformer loaded cascoded JFET/MOSFET output stage instead of the usual tube handling current gain much better.
Almost double the efficiency of a normal Solid State Class A design, no DC on output and many other benefits are taken advantage of in our implementation.
A fully differential architecture using an input phase splitting transformer and summing back at the push-pull output transformer. This solution completely floats the inside of the amplifier isolating it from any external influences.
The design being fully differential is immune to power supply noise.
The power supply for the output stage uses a new breed of rectifier diodes made from a new material called Silicon Carbide. They have no reverse current and switching losses.
When properly applied the rectifier produces no EMI/RFI in the chassis. The result is an amplifier free of grain and fizziness, giving new meaning to transparency and tone.
We use the well-known 5687WA audiophile tube and the highest grade audio transformers. Operating all devices in class ‘A’ produces a fair amount of heat, so the whole chassis is a heat sink. It is the most compact 100-watt class A solid state amplifier available.
The chassis is designed to cope with the heat produced by the components and provide a vibration-free structure to house the components. All the electronics are enclosed in separate compartments to avoid interference between components.
Blending this with stylish aesthetics produced a beautiful sculpture – To be known as Heros.

FAQs
Please read our FAQ before sending us a message.
How is my order processed ?
Once we have received your order and your payment, we issue you an invoice that will be mailed to you with a reference number for your order. Once your order is ready : it will be dispatched to you with insurance and tracking number.
Which payment methos are available in the Online Shop ?
You can choose between Paypal, bank transfer or Credit Card. Please take in consideration that payment via bank transfer will slightly delay the processing of your order as we have to receive your funds on our bank account to confirm your order.
Why are there different estimated delays prior to sending for some of the products
One of the politics of Ana Mighty Sound is that every order is unique and made for a single customer. You will find next to each item an estimated delay prior to delivery. We will do our best to fulfill it before this delay (and most of the time we do).
Please keep in mind that we are a 100% human company working all over the Old World (Europe) and that we do commit to deliver you the best made / best quality product available, and to insure that : this can take some time.
Of course… some of our products are in stock !
Can I specify a courrier for my order ?
Yes you can ! Just drop us a line in the « additional remarks » of your mail order. This may add additional fees to your order. We can work with DHL, TNT, FedEX, UPS, French La Poste or Chronopost.
What if I have received the wrong item ?
In the very unlikely case this would happen just send us a photo of what you received and we will send you a courrier to fetch the item back. Once we have checked it out, we will send you the correct item.
My items are not up to specifications, what should I do ?
This is highly improbable as we use the most modern techniques to insure that our products are up to specs. In fact we even have a dedicated person checking that every single item is in perfect condition prior to shipping. Of course it can happen, but we doubt it seriously. In any case if you were bothered by something : just send us an email and we will sort it out with you.
I am very happy/disappointed with my order and I want you to know it ?
