Description

Please note: this is an API 330-2 card that we have rewired to match the circuitry and specs of an API 325 card.
API 325 (330) 0-40 dB Line Amp, Recap, New API 2520 Opamp Tested Works Well. With original AP2503 triple secondary output transformer. The board has been recently tested and is guaranteed to be working properly. A matching edge connector is included (used, good condition). The card can be used as a mic preamp, but it will only have 40db of gain. Gain is determined by a fixed or variable resistor that is connected to pins 7 and 8 of the edge connector.
We’ll include copies of the original schematic and pinout info.
