Hi guys , i have this site radio which works with the 18 volt battery but not on mains ac power , i suspected the ac transformer (240 Vac to 16 Vac ) , as when i take the transformer out of circuit and supply the 16 v with my bench supply it works ok .
However when i test the transformer out of circuit it seems to work fine , also when i connect the transformer to ac source off the board and connect the transformer output to the board the unit all works fine ..
I am getting 240 AC on the terminals that the transformer connects to as long as the transformer is not connected ... I have tested all the components and replaced the 2 larger caps on the primary side as the esr seemed a bit high ..
Any input would be appreciated ..
