It is definitely built like a battleship. The TO5 transistors are on their heads to reduce vibration damage. Also, decent tantalum caps are used and these, in their day, were incredibly expensive. This all suggests long term unattended working such as CATV etc. A lovely piece of kit - if you ever get a CH1 unit, could I have it Trev?
