 SELF BIASING - That's right, you never have to adjust the bias of the tubes. The benefit is 

that it takes all the hassle out of owning a tube amp, and allows you to run non-matched tubes 
not to mention ensures the best possible sound quality throughout the life of the tubes.

 TUBE RECTIFIED - Designed around the 5Y3GT rectifier and similar types. 

 

The benefit is 

reliability. 

 

With solid state rectification voltage spikes can damage the diodes ensuring an 

eventual trip back to the shop for repair. 

 

Tubes are MUCH harder to damage and if one ever 

did fail, you could change it yourself in seconds and be back in business. 

 

It is also no secret 

that tube rectification generally sounds best - especially in the mid-range.

 REMOVABLE POWER CORD - Uses standard fused IEC connector with hidden spare fuse. 

The benefit is when you move your amp, all cords simply unplug from it. Also allows you to use 
aftermarket boutique cords even though a good power conditioner/isolation transformer would 
have a far greater effect.

 WORLD VOLTAGE COMPATIBILITY - Our power transformers are also our own built to very 

high spec here in the USA and have less then 0.5% failure rate in our amplifiers. This amp 
comes standard with a world voltage compatible transformer that can be wired for any country 
on the planet.

 

 SINGLE TUBE INPUT STAGE - We use a single 6922 dual-triode to drive the output tubes to 

ensure the exact same signature on each channel. 

 

The signature of this tube is the perfect 

compliment to the pentode wired output tubes and 6922's are one of the most popular signal 
tube in the world. 

 

Since tube rolling is a fun way to personalize the signature of your amp, you 

will enjoy knowing there are more different brands and types of 6922 than almost any other 
tube.

 

 We ship the amp with the Russian NOS 6N1P-EV which is a warmer equivalent of the 

6922 and of premium quality.

 

HIGH MASS CHASSIS - Hi density chassis adds 3 more lbs of mass and features a powder 

coat black typewriter finish in a solid walnut base. 

 

Bases are interchangeable with other 

hardwoods.

 SEALED CONSTRUCTION - No ventilation is used because it's not needed. 

 

The benefit is 

that no dust, smoke, or other contaminants get inside to contaminate parts and solder joints. 

 

The internal wiring and parts look new even after 30 years of use.

 ORIGINAL CIRCUIT DESIGN - This amp is not just another knock off of some vintage amp 

from the 60's. 

 

The development of this 

circuit

 was done from scratch and with great care. 

 

Designed to take the magic of our Triode amps to the next level.

 OPTIONAL MATCHING PREAMP - We have a matching preamp that is very synergistic and 

transparent

 

with this amplifier. 

 

It is our model 

CSP2

+

 

 ULTRA LOW NOISE - Less than 1 millivolt of noise and hum (usually 0.4mv). The benefit is 

ultra black backgrounds and inaudible hum on even the most efficient ear speakers.
