About Sonic Imagery Labs Model 990Enh-Ticha Discrete
The Model 990Enh-Ticha is a high performance discrete operational amplifier designed for professional audio application areas where ultra-low noise, low distortion and highly linear uncolored operation is required. It was designed as a high performance upgrade replacement for the Jensen JE990, John Hardy Co. 990A-990C, FiveFish Studios DOA series, Seventh Circle Audio SC25, and Avedis Audio 1122 op-amp style gain block. The pinouts conform to the 990 package, allowing direct replacement. The all-discrete SMT design is similar to the JE990 basic topology but has been completely redesigned to use an ultra-precision differential super-matched transistor pair specifically designed to meet the requirements of ultra-low noise, ultra-low THD, highly linear uncolored audio systems. In addition to the enhanced input stage, the 990Enh-Ticha uses high precision temperature stable power supply independent current sources. Supply independent current sources allow the bias to remain locked at the optimum operating point regardless of power supply voltage. Dual matched pair temperature stable current mirrors, dual matched pair active current loads give the Model 990Enh it's outstanding power supply rejection performance. The enhanced low distortion Class-A output driver stage can sink or source 250mA allowing this module to drive transformers easily. Integrated power transistor heatsinks coupled to a anodized aluminum enclosure keeps the 990Enh-Ticha operating within a wide SOA and does not suffer from Beta droop when driving transformers. Each amplifier is fully tested and meets or exceeds published specifications.
