OVERVIEW:
This is our latest version of the 990 discrete opamp. It’s identical to Deane Jensen’s original circuit published in 1980.
We combine the precision of surface-mount components with Jensen’s original choice of transistors to maintain the authentic sound of the 990. It’s often described as “3D” sounding, natural and true to the source.
After frequent requests, we’re happy to make it available to purchase separately. It will be a great addition to the DIY community, or anyone interested in modding a piece of gear.
