API 525 Clone Build

qmp audio built 525!6efbd504a6db11e2855722000aa800e1_7

We love the new addition to Gunpoint’s 51x Rack.  qmp audio Built this lovely API 525 compressor.  This pair of optionally linked compressors have a real sweet tone.  We’re totally looking forward to be running these out on some vocals and bass tracks.

This 525 has an LED gain reduction meter.  Two EA 2623-1 transformers feed the output and sidechain.  This circuit uses 3 2520 opamps ( that’s quite a bit of soldering those tiny bits ).  qmp audio chose to replace the originals 2510 opamp for a Lundahl LL1540 input transformer.  Why not?  A little extra iron can be a good thing.  Another modification from the original 525 is the addition of a variable attack time.
