The heart of a distribution system providing TV reception for about 40 bungalows, this is a typical head-end from the early 1970s. The unit was custom built on a steel plate, using amplifiers, combiner and splitters. Connections were unscreened. Power was 12VDC from the PSU at bottom right. These boards were generally adequate for VHF TV, but struggled to provide adequate signals levels for UHF, because of the much greater cable and tap-off losses. These boards were very reliable, and I’ve often removed 30 year-old examples in full working order.
