Identical in feature and functionality to our Black Emerald B8971 clock, this version sports an enclosure in Krell grey, similar to the beautiful sanded and anodized finish on Legacy Krell Audio gear. PCB's are done in flat black, colon towers are Sterling silver tube, and the front beacon and PCB LEDs are white ( even tho they both look blue) vs. the green LED’s used on the Black Emerald. The flat head bezel screws are MoS2 finished to match the beautiful gray anodized aluminum. All visible components are black vs. the green used on the earlier clock. This is a ONE-OFF only and will not be available for sale unless we get requests for at least 10 of these! The tubes are the problem, I would gladly make more of these were there tubes available.
