Burr-Brown OpAmp Preamp II

This is the second of my preamps based on the high performance Burr-Brown OPA2134PA. This one has been custom built for a fellow in the US. This build has additional and switchable inputs-as you can see. The bottom and center row of inputs are selectable by the switch, the top row of connections is the output. See the DIY OP Amp Based Preamplifier page for more details.
