The 1122 was originally made for replacement opamps for the repair for the many older gear we've worked on, and was also used in custom made preamps and prototypes for our use.

The 1122 combines classic design with today's high quality choice of components to make it operatable with a wider voltage range and exhibit slightly lower noise than what was possible before. Using no IC's, no JFET's, and no surface-mount components, the 1122 is an evolution of where our favorite opamps from the past left off.

PLEASE NOTE: WE DO NOT SELL THE 1122 OPAMP FOR DIY PROJECTS.
