Considered by many as the best sounding 2520 vintage replica on the market!
The SA-25 is a 1:1 fully discrete 9 transistor replica of the famous Huntingdon 2520 discrete operational amplifier found on the early API consoles from the 70’s.
It is used on our SA-4000, 25609, 312+and 312-5T. It can also be used as an upgrade to other OEM units and DIY projects.
It is sonically identical to an early 70’s Huntingdon 2520 Op-Amp
Each op-amp comes with PCB pins and a 3 year warranty.
