| br>I just finished building a Moog ladder filter in a PAiA 4700 format with appropriate signal levels. I used the new FPE print-on-aluminum and the panels come out very close to original. They are anodized so have a matte finish instead of glossy. I used the YUSynth PCB since it fit perfectly behind a 2-wide panel. I also found some great knobs that look almost identical to the original 4700 knobs - details are on my PAiA 4700 Modular Synthesizer Rebuild page.
