Hi Bob - I’ve seen you videos, great work. I especially love the work you did restoring that PRI 118 Royal Scintillator. What a beautiful instrument. Glad you are here. Cheers, Tom

Re: Not something you see everyday..

Steven is correct, resolution at 661 is only about 14%. These detectors were not built for spectroscopy use even when new, but were part of a portal monitoring system.

Re: GS-USB-PRO Sneak preview

Steven - Great looking product with nice connectivity. Can you reveal voltage range/power info and USB audio specs (eg. bit rate and resolution, S/N ratio, DAC). Fantastic so far! Tom
