Hi RJB
I took the fitting down and had a look..... no name on the transformer but the info on the label was as follows: Model No A2321012S
PRI 230V
SEC 12V-210VA...
I have just changed a 2 gang switch to a 2 gang dimmer switch. One of the fittings running 5 - 50W halogen spots runs fine. The other fitting that has a wire wound transformer running 8 - 20w 12v LV halogen capsules buzzes loudly unless it's off or fully on. Any ideas for reasons/solutions out...
