SONATAS - Reference 60W+60W
Stereo Valve Tube Power Amplifier
Retired Product
The input stage is 12AT7 SRPP direct coupling to 12AU7 driver stage , The driver stage use high quality capacitors to Gold Lion KT88 power tube , The KT88 work at P-P UL mode to driver TANGO XE-60-5 high quality output transformer , The XE-60-5 output transformer has very low Insertion Loss 0.21dB only. ( Many tube power amplifier in Hi-End audio market , Their have the output transformers is over 1dB Insertion Loss . only about 10% very high price tube amplifier use under 1dB Insertion Loss of output transformer ) . The output transformer has low insertion loss is very important , the best of the best is 0 dB Insertion Loss , The output transformers for High End tube amplifier need under 1dB Insertion Loss . The Insertion Loss over 1.5dB output transformer will lost many low level music.
The Sonatas-Reference have RCA and Balanced two version, the price is same.
The components , NFB value , tube type , circuit all select by listen test.
