 The [[http://www.ucapps.de/mbhp_opl3.html|MBHP_OPL3]] module originally has three TL074 op-amps, and a circuit that needs +/-12V bipolar power supply.
-In Wilba and nILS sammichFM, they use two OPA4348 rail-to-rail op-amps, that can be powered by 5V.
+In Wilba and nILS [[sammichfm|sammichFM]], they use two OPA4348 rail-to-rail op-amps, that can be powered by 5V.
 Sauraen suggested another 5V rail-to rail op-amp, the MCP6004, which is pin compatible with the TL074, and a way to modify the OPL3 module to use these.[[http://midibox.org/forums/topic/18492-mbfm-5v-option/]]
