The Wright Audio
Royale SE

Single-Ended Triode Stereo Power Amplifier
 



 

The Wright Audio Royale SE Power Amplifier is a single-ended, triode-connected tube stereo power amplifier.  Properly designed, amplifiers of this category are characterized by a more vivid, clear and harmonically-rich sound than the higher-powered 'push-pull' amplifier type.

However, the Royale SE Power Amplifier provides lower distortion, wider frequency response and greater listening quality than other single-ended designs, even while using no overall loop circuit feedback.  This is due to a careful selection of parts chosen based on sound quality through extensive listening tests and with operating parameters chosen for lowest distortion.  Like all other Wright Audio amplifiers, polypropylene and foil capacitors and transformers created for wide bandwidth and high resolution have been employed.

The tubes are 'self biased' and the amplifier requires no operating adjustments.

Although the Royale SE Stereo Power Amplifier may be used with any preamplifier and a high efficiency speaker system, it was created to be used with the Royale SE Series 2 Integrated Amplifier and an external electronic crossover for tri-amplification purposes.   In this configuration, the Royale SE Integrated Amplifier's power amplifier section drives the tweeters, the Royale SE Stereo Power Amplifier drives the midranges and a transistor amplifier drives the (sub) woofers. 

The listening result is far lower levels of distortion of all types and complete power transfer from the amplifier directly to the speaker drive units for the highest efficiency.  This means the entire system will sound much more 'alive' and play significantly louder with less strain, making the lower powered single-ended amplifier concept the best you've ever heard. 

In addition, a tri-amplified system will allow the listener ultimate flexibility for correct octave to octave tonal balance by adjustment of the relative volume levels of the tweeter, mid-range and woofer to compensate for the room environment, program material (especially playing vinyl records) and general listening preferences.

Used in this manner, the Royale Single-Ended Triode Power Amplifier will suddenly involve you more intimately with the music you love.

Approved Replacement Tube Sets

All tubes are tested and screened for both AC and DC parameters under identical electrical operating conditions as is used in the amplifier to ensure quality.

The Royale SE Power Amplifier requires that the 6N1P have matched sections and EL34 types be matched pairs for equal channel balance and full sonic imaging.

It is recommended that the 6N1P and 5AR4 tubes be replaced half as frequently as the EL34 / KT77 type tubes.  The EL34 / KT77 tube pair should be changed approximately every 1500 hours.

(1) 6N1P (Balanced Sections) and (1) 5AR4  -  $ 35
JJ KT77 Matched Pair  -  $ 45
JJ 6CA7 Matched Pair  -  $ 42
Matched Pair Reproduction Tung Sol EL34B  -  $ 58

Use of Tubes Not Approved

Single-ended amplifiers require tubes of the highest quality for amplifier reliability.  Sadly, there are good-sounding tubes which may be used in push-pull amplifier designs but are not suitable for use in any single-ended amplifiers.  Using them will cause the tubes to fail prematurely and likely cause damage to the amplifier.

Use only tubes recommended by Wright Audio.  Evidence of the contrary causing damage to an amplifier is not covered by the Warranty.
