Vintage Output Bundle


Add the vintage sound of a discrete opamp and transformer to your EQP5 Passive Equalizer or OLA5 Opto Compressor. The bundle is based around our 2523 transformer which is based on the 2503 output transformer found in vintage API consoles.

Choose Your DOA.

The vintage output bundle does not come with a DOA (discrete opamp). Bring your own or choose from our selection of DOA kits.


  • Custom, USA-wound output transformer
  • Your choice of discrete opamp
  • NOS tantalum capacitor
  • Transformer mounting hardware included

The vintage output gives signals a more visceral, forward feeling that helps them translate clearly in a mix while requiring less level to do so. The solid-state Pultecs, the sound of which many engineers claim to be sweeter than that of the earlier tube units, use the same DOA/transformer output scheme.
