We have a set of Byron SD86 wireless doorbell chimes and the bellpush
is in need of replacement. The SD86 model appears to have been
airbrushed out of history - can't find any mention on Byron's web
site, and B&Q only sell SX and TX models - does anyone know of
anything compatible with the SD range, or have we got to buy a new set
- in which case I'll buy something else from somewhere else, as long
as it has a longer potential lifespan
