The gar1731 DOA PCB is the printed circuit board only, that is required to complete the gar1731 Discrete Operational Amplifier build. This board has been designed by Gary Barnett of Barnett Industries. This DOA is an eight transistor amplifier modeled after the legendary Melcor 1731. For those who do not know it, many of the engineers responsible for the Melcor 1731 left Modular Audio Products around 1968 to join forces with Saul Walker when he started API. The starting point for the famous API 2520 was indeed the Melcor 1731. Back to the beginning I guess one could say!

The gar1731 sounds absolutely fantastic in our all of our kits and modules. Overall, it's sonically very similar to the sound of a 2520. The gar1731 has a slightly smoother bottom and top, while simultaneously retaining the ever familiar aggressive, forward midrange we love about the 2520.

Some of the applications the gar1731 DOA 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
Minimum load impedance is 75 ohms for full output voltage
Power supply voltage is bi-polar +/- 12 VDC to +/- 20 VDC
A complete PDF assembly guide including BOM will be provided via email after purchase
It should be noted that all 8 transistors are currently in production and easily obtainable

gar1731 Full Kit Bundles including the PCB, are also available

***Please note: This item is a raw, unpopulated PCB only. All other components in pictures are for informational purposes only. This assembly is not for the beginner. Good assembly and solder skills are a must!
