I suppose most 405 tellies didn't need a lot of gain & high performance sync gubbins as they'd be used in strong-ish signal areas. I understand they made fringe models with extra gain & flywheel line & frame sync. I suppose in fringe areas viewers would notice when performance dropped off as valves aged, but in strong signal areas old bangers on their last legs would still work to a fashion. Mr & Mrs public seemed happy if they got a picture..
