Grass Valley 8502 Video DA cards

These Grass Valley model 8502 Equalizing Distribution amplifiers were pulled from 2 frames that were installed in a corporate editing facility.  The cards are very clean, and each output has been tested using a color bar generator, with the outputs viewed on a WFM, Vectorscope and Sony PVM monitor.  We checked for jitter, intermittent operation, and variations in gain across the outputs.

If you are shopping for replacement cards for a GVG card cage, you know what to expect.  GVG has set the standard for professional video for decades, and their commitment to intelligent designs and rugged specifications are matched by few companies today.

All 12 DAs have been retested thouroughly: all 6 outputs pass for Level and EQ adjustments, and hum & noise measurements.  They all are in excellent working condition.
