I fixed it by fitting a Smartass, easily heard via headset & impossible
to ignore, neither of which can be said for stall warner even when
working - which sounds as a very distant minor squeak using modern
headsets!

fitted in G-YETI (RS Components part No 317-443) but I'm struggling to get
it to work correctly - despite changing the switch for a new one today.
