I don't think it ever made it to production, but the idea of driving the CRT directly from the detector resurfaced in early work on transistorised TVs. The video output stage was difficult - high voltage and high frequency - which wasn't solved until the AF118 was made. One possible solution was a power IF stage with a high slope CRT. This was regarded as impractical.
