The Wright Audio Royale SE Power Amplifier is a single-ended, triode-connected tube stereo amplifier electrically and sonically matched to the Wright Audio Stereo Control Preamplifier LT-6P.   This power amplifier requires an active preamplifier (with gain) for proper operation.

It can accommodate KT77, EL34 or 6CA7 output tubes and provides 7 watts per channel in pure Class A service.

Due to the 'single-ended' circuitry, it is characterized by a much more vivid, clear and harmonically-rich sound with greater dimensionality than solid-state, Class D or even higher-powered 'push-pull' amplifier types whether using tubes or transistors.

It requires being used with higher efficiency speakers having a sensitivity rating of at least 90 db / 1 watt / 1 meter for a satisfactory experience.  This sensitivity number will be found in the intended speaker's specifications.

This power amplifier provides greater clarity and more dynamics than other tube single-ended designs.  This is due to a careful selection of parts, a circuit topology and operating parameters all chosen for sound quality through extensive listening tests. 

Like all other Wright Audio amplifiers, polypropylene and foil capacitors and output transformers created for wide bandwidth and high resolution have been employed. 

The tubes are all biased into "Class A" service and the amplifier requires no maintenance or adjustment other than normal tube replacement.

There are no solid-state devices, integrated circuits, transistors or circuit boards anywhere in the amplifier.

The music signal directly passes through just two capacitors and two vacuum tube stages per channel to preserve the integrity of the signal source.
