DIY-990 Op-Amp Kit


This kit includes the PCB and all of the parts needed to build your own JE-990 op-amp.

Designed to the specifications of Deane Jensen’s now famous JE-990 paper published in the February 1980 AES journal. The DIY-990 utilizes a bottom layer mounted SSM2212 Analog Devices dual matched transistor. This surface mount device (SMD), along with the two SMD bypass capacitors, and six PCB mounting pins arrive pre-soldered to the PCB. Only the thru-hole components are left to install.

PCB layout by MNATs in 2520 format.

The DIY-990 PCB is made and assembled in the USA. 

Recommended for intermediate builders.
