Review on Ximimark Preamp Amplification OPA2134 OPA2604 by Jeff Westra

I actually had all the parts I needed to build one of these from scratch but I didn't have a breadboard so while browsing Revain I came across these little boards and thought it would save me time and look better than what I could do with my own hands. myself. I added blue trim strips as an input attenuator. This served to modularize the synthesizer: I had to amplify the signal from two Mos-Lab 921-B VCOs from 0.53V to 1V because the Synth-Werk 6401M Bode ring modulator needs at least 1V to work properly.
