"Ah, but David is limiting us to valve technology." Hi Peter,
that's right, one has to abide by the rules which means only using the technology of those times and as the HMV 1804 was made in 1946 it has to be valves. In 1946 big octal valves were still the norm and certain miniature all glass valves were beginning to appear in equipment but not in the HMV because the 1804 is essentially a pre-war set. The pre-war model was the 1800.
