CA-0252 (OEM) - Add on

The CA-0252 Discrete Opamp is the exact same circuit as the CA-0252 built kit. The PCB is slightly smaller to fit in the potting shell. During the resizing of the PCB a few components got moved around. Besides that, The component difference listed below.Input transistorsThe kit version uses BC237C transistors. For the potted version we are using custom made BC414C transistors.Interstage NPNsThe kit version uses custom made TIS97 transistors. For the potted version we are using new-old-stock Texas Instruments TIS97 transistors. We have enough stock to build just over 11,000 opamps so it should last us a while!The CA-0252 Discrete Opamp only ships with the longer terminal pins so there is no issue in a 2500 etc that may have other components under the opamp footprint. These longer pins impose no issues when used in a situation with no components under the amp. Just leave them long. If you have an old school situation where the amps are soldered directly to the PCB, just solder them in an
