SQ10 DISCRETE OPAMP
This is a copy of the original Quad-Eight AM10 opamp used in their legendary Pacifica, Ventura, and Coronado consoles. It's designed to work with up to +/- 28V supply rails, for maximum headroom. My version is true to the original design, but uses higher quality components such as 1% metal film resistors, C0G (NP0) ceramic capacitors, and higher wattage output resistors. The input transistors are matched by hand and each opamp is fully tested.
It's available both in the popular 2520 format, and the original format for use in Quad-Eight consoles.
