CAPI MEC1731 Discrete Opamp - NEW!

AMAZING NEW OPAMP IN STOCK AND READY TO SHIP

These are assembled and tested by Resistance Audio. We find that the MEC1731 is the perfect option for all of CAPI's EQ's. This opamp is warm and smooth, with increased clarity and punch compared to the gar1731.

The MEC1731 is CAPI's take on the vintage Melcor 1731 opamp, and is the most accurate recreation of this opamp that we know of.

The MEC1731 Discrete Opamp is a fully assembled, rigorously tested discrete operational amplifier.

From CAPI:  Such a version has never been realized before as far as we know. Specifically because we are being as faithful as possible to the exact type of parts used in the original version. I know this because I purchased four AML27 amplifier cards some years ago. After having them forever, and practicing on a 2520, I decided to take one of the 1731 amps apart and see if the popular DIY versions were accurate. The biggest difference is how different they sound when using the original transistors and not substitutions. Like with the CA-0252 we are using single layer capacitors and carbon film resistors. After all, everything changes everything.

The MEC1731 Discrete Opamp only ships with the longer terminal pins so there is no issue in a 2500 etc that may have other components under the opamp footprint. These longer pins impose no issues when used in a situation with no components under the amp. Just leave them long. If you have an old school situation where the amps are soldered directly to the PCB, just solder them in and cut the pins off.

Some of the applications the MEC1731 Discrete Opamp 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 +/- 18 VDC
