My 1950s B7G Barker-88 had a triple-capacitor smoothing-can that definitely needed replacement - it went too-hot-to-touch after an hour or so of being powered-up.
The caps from the 6AT6 phase-splitter to the output-valves' grids were probably US-WWII-surplus Sprague 400VW items - opinion varies on these [they're the kind with a dull plated metal body, paxolin end-plates and red printed lettering] - some claim they are paper-in-oil so should be good even after all these years - but I replaced them with modern 630V-working yellow Kemet ones just to be on the safe side.
And I agree - this radio needs to be used, rather than being sat on a shelf to be worshipped like some sacred relic.
