SV101647.JPGOPA2134 Inside the Chip amp preamp II3609 viewsYou can see how compact the boards are. The yellow caps are MPX 0.47uF and 220uF low ESR electrolytics store power from the voltage divider network (virtual ground). Computer stand-off keep the brds. off the case and are fitted with rubber grommets to control cct. resonance and vibration. More details are available at the DIY OPA2134PA Preamplifier Project page.Jul 08, 2008

SV101673.JPGOPA2134 Preamp II with selectable inputs3190 viewsOP amp based preamp, that provides two pairs of selectable inputs, volume and balance control and 6dB of gain. A compact cct. with the only links on the cct. brd. being silver earth links, packs a lot of performance into a solid cast aluminum case. With distortion figures as low as .00008%, solid pure silver wire throughout, WBT silver solder and each of the the two circuit boards having their own virtual +/- power supply plus additional tar and aluminum damping/shielding internally this preamp can deliver. I hope the new owner enjoys listen through it as much as I have enjoyed building it. See the DIY OPA2134 Preamplifier page for more build details.Jul 08, 2008

SV101672.JPGBurr-Brown OpAmp Preamp II3261 viewsThis 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. Jul 08, 2008

MicroStudio.JPGDIY Mini Recording System5366 viewsBased around the Sony ECM-MS957 stereo microphone (discontinued) and Cowon i6 mp3 player, I built a quality mic preamp to complete this mini-recoding studio. All components are high quality and excellent recordings can be made with no other equipment required. The idea is to keep this portable but to retain quality of recordings. From microphone to digital transfer provides clean, crisp, noise free recording. All battery powered the system sits easily on a table top at your local jazz club to record the music and the vibes.Jun 27, 2008
