Opus Universal Reference Preamplifier “new PCB layout”, that fully take advantage of the new GQT Tape Machine. Kostas Metaxas is currently updating the PCB [Printed Circuit Boards] for the OPUS so it can offer extra modules…
1. RIAA Phono Stage – single ended & push-pull DC
2. DAC or ADC
3. Record and Playback Electronics [for GQT]
Also, there will be the option of offering “Vacuum Tube” stages as well.
“I’m still using Protel 99SE since it allows me to easily generate 3D PCBs in Solidworks for my modeling [to make sure things fit].”
