garOA10 Neumann OA10 ver.3

This Discrete Operational Amplifier has been created by Gary Barnett of Barnett Industries. This DOA is a twelve transistor amplifier modeled after the legendary Neumann OA10. Gary has reformatted the layout to match the 2520 footprint. The original OA10 layout was a completely different proprietary footprint. Very big sounding with a warm but still punchy low end, and a nice ‘HiFi’ top end. Expensive sound!

The original OA10 was actually designed to run on +/-22 V rails but it should be noted that the garOA10 has been rigorously tested on +/-28 V rails with great success. So as a bonus, the garOA10 can be used in the GDIY 51x format which utilizes +/-24 V rails.

These started out as an experiment at Gary’s shop, hence the original garXXXX moniker.

Some of the applications the GAR OA10 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 +/- 28 VDC

Fully built to perfection in Canada with a 1 year warranty.

Assembled with Kester solder.

These can be also build to order.
