JLM25HV/JLM25HVFET Discrete Opamp

Projects > JLM25HV/JLM25HVFET Discrete Opamp

The JLM25HV is JLM Audio’s take on the classic API discrete opamp. The 25HV includes various improvements upon it’s vintage progenitor, including the ability to run on up to +/-34vdc. The 25HVFET model replaces the standard bipolar input transistor with a high-impedance FET for use in circuits where a DI runs directly into the opamp.


  • Capable of running on +/-12v to +/-34v
  • Layout reduces DC offset on the output
  • LED indicator on PCB
  • Drop-in replacement for any API2520-style discrete opamp

Price: $60 for assembled unit
