Most Philco 20 suffer from that.
Worst yet, those switches that are dedicated switches (not combined with volume pots) are not easy to disassemble, unlike those in volume regulators.
And, as I said, about half the radios I've done with volume pot switches had dirty contacts that resulted in full open. Simple alcohol washing did the trick.

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.
