API 2520H – any info/history/etc.
May 6, 2010 Recording
Hi, I bought a vintage API 550A that someone has replaced one of the two 2520 opamps with a 2520H – does anyone know anything about when these were made, what they were originally used for? their quality/sound or any other interesting facts they’d like to share?
