There are no clips over the valves in a 274A, which, for those who don't know , is a mid 1930s TRF - one of the 'Superinductance' series in which the valves are all either 4 or 5 pin types. A clip would help to keep the output valve firmly seated in it's socket. From the way it behaves there is more than one intermittent socket in the valve base which has to be tackled. Basically this radio is 'showing it's age.
