Generator, Signal CT212

Here's another example of military over-engineering - although the manufacturer is unknown. The CT212 was built for the Royal Navy from around the late 1950's.

It has an operating range of 85KHz to 32MHz across 7 switched ranges. It has an attenuated output of 100mV max and a frequency deviation of 30KHz - all this in a sealed aluminium case that should have a lid containing various probes and connectors!

The unit may be powered either by 12v battery or by AC power from 110V to 250V. It contains a total of 7 valves.
