For sale is an Audio-GD Moon discrete opamp (OPA). This is the dual, i.e. two channel, version. Includes 50mm long standard extension lead. (The extension lead can allow the 24x24x40mm size of this opamp to be repositioned in devices that don't have room for it in the upright position.)
Audio-GD sells these for $25 plus $3 for the extension lead plus $20 for shipping from China to USA (total of $48). I'll sell mine for $25 including shipping in the USA.
Please make certain your device uses a dual channel OPA rather than two separate single channel OPAs.
