The BB2521 TI-5534 Full Kit Bundle is a full and complete parts kit with everything required to complete a BB2521 IC-Discrete Operational Amplifier build. The original concept of the hybrid opamp is far from a new one. This circuit is heavily based on the output stage of the old B&B EQF-2 equalizer. B&B was eventually bought by Aphex somewhere around 1980. Just about every major pro audio manufacturer using chips and output transformers has used some variation of this concept including Aphex, ADM, Neve, Harrison, UREI and more. The goal for this kit is low cost and ease of build while still being a very good sounding and useful operational amplifier. The BB2521 is all of that. This kit comes with a Texas Instruments NE5534. For kits containing other IC's, please visit the Hybrid subcategory. Some of the applications the BB2521 opamp can be used for: Microphone Preamplifiers Line or Booster Amplifiers Lossless Combining Amplifiers Balanced Transformerless Amplifiers Equalizers and Compressors Additional features and specs: Industry standard 2520 footprint for plug-in or PC mount connections Low noise, high power output Low distortion Power supply voltage is bi-polar, consult IC's datasheet to determine operating voltage A complete PDF assembly guide including BOM will be provided via email after purchase ***Please note: This item is a complete parts kit and PCB bundle. Full and complete assembly is required.
