Well ... a small diode is inconspicuous, could be easily hidden and allows to keep the tube count which does preserve the authentic look. And with one diode vs many tubes that still leaves it at being a tube radio. Icon_smile

Speaking of which, a semiconductor detector is as old as the tube one. Actually older. It's just it did not assume the shape of a small diode for a while and was made of lead and sulfur and not Germanium.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
